  • Voltage Stability Index and Voltage Deviation Improvements using Intelligent Algorithms for Capacitor Sizing and Placement
    Voltage Stability Index and Voltage Deviation Improvements using Intelligent Algorithms for Capacitor Sizing and Placement Bhatt, Y.H.; Bhatt, D.V.; Pakka, V. H. Voltage stability of each bus of an electrical distribution system along with the deviation of voltage magnitudes from the tolerance limits are two of the most common but significant issues in the present day distribution networks. This work is carried out with the objective of identifying the optimal location and ideal sizes of capacitors to be used in a radial distribution network for alleviating the above problems. An intelligent two-stage methodology is used that employs genetic algorithm and neural networks in order to achieve this objective. By analyzing the load flow study of the base case of load profile, voltage deviation and voltage stability indices are calculated for each node of the system. From these indices, the candidate buses are identified for the capacitor allocation in stage one of the methodology. Then, the combination of two artificial intelligent algorithms based on modern learning methods are employed to identify the ideal sizes of the capacitors for operation throughout the day. This methodology is implemented on a 33 bus radial distribution network. The results of these intelligent algorithms predict the ideal sizes of capacitors with optimal locations, providing a stable system with a smooth voltage profile across the entire duration of the day.

  • Improved occupancy monitoring in non-domestic buildings
    Improved occupancy monitoring in non-domestic buildings Ekwevugbe, Tobore; Brown, Neil; Pakka, V. H.; Fan, Denis Measuring occupancy can facilitate energy efficiency in non-domestic buildings, when control systems are able to adjust heating and cooling based on demand rather than fixed schedules. The variable “occupancy profile” itself is rarely considered as a control system parameter in building energy management systems (BEMS), and this is largely because reliably measuring occupancy in the past has been too difficult, expensive, or a mixture of both. Occupancy detection is possible using e.g. CO2 sensors, passive infra-red (PIR) detectors, which can provide a basic trigger for services, but the actual occupancy count, and therefore the expected load on building services, requires a step change in instrumentation. Advanced occupancy sensors developed from a heterogeneous multisensory fusion strategy offer this, improving control system performance, e.g. turning off services out of hours, and not over-ventilating, saving energy, while not under-ventilating during occupancy, benefitting comfort and health. While this is the case, there is a shortage of any systematic methodology for developing robust and reliable occupancy monitoring systems from heterogeneous multi-sensory sources. In this paper we describe an innovative sensor fusion approach utilising symmetrical uncertainty (SU) analysis and a genetic based feature selection for building occupancy estimation.

  • Design and Analysis of Electrical Distribution Networks and Balancing Markets in the UK: A New Framework with Applications
    Design and Analysis of Electrical Distribution Networks and Balancing Markets in the UK: A New Framework with Applications Pakka, V. H.; Rylatt, R. Mark We present a framework for the design and simulation of electrical distribution systems and short term electricity markets specific to the UK. The modelling comprises packages relating to the technical and economic features of the electrical grid. The first package models the medium/low distribution networks with elements such as transformers, voltage regulators, distributed generators, composite loads, distribution lines and cables. This model forms the basis for elementary analysis such as load flow and short circuit calculations and also enables the investigation of effects of integrating distributed resources, voltage regulation, resource scheduling and the like. The second part of the modelling exercise relates to the UK short term electricity market with specific features such as balancing mechanism and bid-offer strategies. The framework is used for investigating methods of voltage regulation using multiple control technologies, to demonstrate the effects of high penetration of wind power on balancing prices and finally use these prices towards achieving demand response through aggregated prosumers.
  • Exploring Smart Grid Possibilities: A Complex Systems Modelling Approach
    Exploring Smart Grid Possibilities: A Complex Systems Modelling Approach Rylatt, R. Mark; Snape, J. Richard; Allen, P.; Ardestani, B. M.; Boait, Peter John; Boggasch, E.; Fan, Denis; Fletcher, G.; Gammon, Rupert; Lemon, Mark; Pakka, V. H.; Savill, M.; Smith, Stefan; Strathern, M.; Varga, Liz Smart grid research has tended to be compartmentalised, with notable contributions from economics, electrical engineering and science and technology studies. However, there is an acknowledged and growing need for an integrated systems approach to the evaluation of smart grid initiatives. The capacity to simulate and explore smart grid possibilities on various scales is key to such an integrated approach but existing models – even if multidisciplinary – tend to have a limited focus. This paper describes an innovative and flexible framework that has been developed to facilitate the simulation of various smart grid scenarios and the interconnected social, technical and economic networks from a complex systems perspective. The architecture is described and related to realised examples of its use, both to model the electricity system as it is today and to model futures that have been envisioned in the literature. Potential future applications of the framework are explored, along with its utility as an analytic and decision support tool for smart grid stakeholders.

  • Advanced Occupancy Sensing for Energy Efficiency in Office Buildings
    Advanced Occupancy Sensing for Energy Efficiency in Office Buildings Ekwevugbe, Tobore; Brown, Neil; Pakka, V. H.; Fan, Denis Control systems for Heating, Ventilation and Air-conditioning (HVAC) in non-domestic buildings often operate to fixed schedules, assuming maximum occupancy during business hours. Since lower occupancies usually mean less demand for HVAC, energy savings could be made. Air quality sensing, often combined with temperature sensing, has performed sufficiently in the past for this if maintained properly, although sensor and control failures may increase energy use by as much as 50%. As energy costs increase, building controls must meet increasingly stringent environmental requirements, increases in building services complexity, and reduced commissioning time, all placing ever higher demands on sensing, with a standing requirement to improve reliability. Sensor fusion offers performance and resilience to meet these demands, while cost and privacy are key factors which are also met. This paper describes a neural network approach to sensor fusion for occupancy estimation. Feature selection was carried out using symmetrical uncertainty analysis, while fusion of sensor features used a back-propagation neural network, with occupant count accuracy exceeding 74%.
  • An NSGA-II based Multi-Objective Approach for Distribution System Voltage Control
    An NSGA-II based Multi-Objective Approach for Distribution System Voltage Control Pakka, V. H.; Rylatt, R. M. The aim of this work is to offer a voltage control strategy for distribution networks that experience voltage unbalance due to single phase and unbalanced loads and voltage rise due to high penetration of Distributed Generation units. The objectives are minimization of voltage imbalance on each node and total power losses on the entire network. The control of node voltages by Distributed Generation units has potential to clash with the more traditional method of voltage control adopted by Distribution Network Operators namely, tap changing voltage regulators and shunt capacitors. We look at a coordinated method of voltage control that solves the multi-objective optimization problem of voltage profile improvement and power loss reduction using a Pareto optimal and elitist evolutionary optimization algorithm called Non-dominated Sorting Genetic Algorithm II (NSGA-II). The study system is the IEEE 123 bus distribution test feeder which is highly unbalanced and includes most of the elements of a real network.
  • An Object-Oriented Framework for Analysis of MV/LV Distribution Systems
    An Object-Oriented Framework for Analysis of MV/LV Distribution Systems Pakka, V. H.; Rylatt, R. M. The interest of this work is in designing and developing a simulation package for comprehensive analysis of a distribution system based on object-oriented principles. Towards such an objective, we propose a design of a framework based on an object-oriented approach that is capable of handling such features and yet is simple and flexible enough for further extension. Here, we present a novel derivation of an object oriented methodology to firstly model the various components of a present day distribution system, and then to solve for the power flows across the system. Innovative aspects of the implementation of the derived system are how the various components are represented for power flow calculations using a standard backward/forward algorithm. An IEEE test feeder is used to demonstrate the framework. This work is of interest to model developers, distribution network planners, software designers and most importantly to users in the academia and industry. This work was conducted as part of the AMEN (Agentbased Modelling of Electricity Networks) project, funded by the Engineering and Physical Sciences Research Council in the UK under Grant Reference EP/K033492/1.
  • An Agent Based Model for Optimal Generation Mix based on Price Elasticity of Aggregated Consumer Demand
    An Agent Based Model for Optimal Generation Mix based on Price Elasticity of Aggregated Consumer Demand Pakka, V. H.; Ardestani, B. M.; Rylatt, R. M. This work has its interests in the relation between the generation mix within a power system and the elasticity of demand based on the prices emerging from the short term electricity market. The paper starts by describing a new agent-based modelling framework that involves electricity producers, consumers and suppliers as agents participating in a market environment. The framework allows for investigating the effect of demand elasticities on bidding of generators in the short term market and its influence on their revenue in the long term. We focus on the increasingly important issue of renewable technology such as wind generation and the volatility it brings into the electricity market. Specifically we investigate three scenarios with varying mix of generating technologies such as coal, gas and wind turbines and measure the aggregate demand response to signals such as the System Buy Prices (SBP) emerging out of the balancing market. This work was conducted as part of the AMEN (Agentbased Modelling of Electricity Networks) project, funded by the Engineering and Physical Sciences Research Council in the UK under Grant Reference EP/K033492/1.
  • Balancing electricity supply with distribution network constraints
    Balancing electricity supply with distribution network constraints Boait, Peter John; Pakka, V. H. The need for electricity demand to adapt to distribution network constraints and intermittent supply from renewable generators is widely recognised. However addressing both these goals simultaneously with a single demand side management scheme is difficult within a deregulated industry framework. This paper describes a scalable method by which electricity suppliers can shape demand from domestic and SME consumers, particularly that arising from adoption of heat pumps and electric vehicles. A process is proposed by which Distribution Network Operators notify a maximum power profile for each connection to the supplier, who then uses it to shape demand from each consumer so that DNO limits are satisfied as a priority, and demand responds to supply availability as far as possible.
  • CASCADE: An Agent Based Framework For Modeling The Dynamics Of Smart Electricity Systems
    CASCADE: An Agent Based Framework For Modeling The Dynamics Of Smart Electricity Systems Rylatt, R. M.; Gammon, Rupert; Boait, Peter John; Varga, L.; Allen, P.; Savill, M.; Snape, J. Richard; Lemon, Mark; Ardestani, B. M.; Pakka, V. H.; Fletcher, G.; Smith, S.; Fan, D.; Strathern, M. The Complex Adaptive Systems, Cognitive Agents and Distributed Energy (CASCADE) project is developing a framework based on Agent Based Modelling (ABM). The CASCADE Framework can be used both to gain policy and industry relevant insights into the smart grid concept itself and as a platform to design and test distributed ICT solutions for smart grid based business entities. ABM is used to capture the behaviors of diff erent social, economic and technical actors, which may be defi ned at various levels of abstraction. It is applied to understanding their interactions and can be adapted to include learning processes and emergent patterns. CASCADE models ‘prosumer’ agents (i.e., producers and/or consumers of energy) and ‘aggregator’ agents (e.g., traders of energy in both wholesale and retail markets) at various scales, from large generators and Energy Service Companies down to individual people and devices. The CASCADE Framework is formed of three main subdivisions that link models of electricity supply and demand, the electricity market and power fl ow. It can also model the variability of renewable energy generation caused by the weather, which is an important issue for grid balancing and the profi tability of energy suppliers. The development of CASCADE has already yielded some interesting early fi ndings, demonstrating that it is possible for a mediating agent (aggregator) to achieve stable demandfl attening across groups of domestic households fi tted with smart energy control and communication devices, where direct wholesale price signals had previously been found to produce characteristic complex system instability. In another example, it has demonstrated how large changes in supply mix can be caused even by small changes in demand profi le. Ongoing and planned refi nements to the Framework will support investigation of demand response at various scales, the integration of the power sector with transport and heat sectors, novel technology adoption and diffusion work, evolution of new smart grid business models, and complex power grid engineering and market interactions.
