Bollen Math H. Integration of Distributed Generation in the Power System


The integration of new sources of energy like wind power, solar-power, small-scale generation, or combined heat and power in the power grid is something that impacts a lot of stakeholders: network companies (both distribution and transmission), the owners and operators of the DG units, other end-users of the power grid (including normal consumers like you and me) and not in the least policy makers and regulators. There is a lot of misunderstanding about the impact of DG on the power grid, with one side (including mainly some but certainly not all, network companies) claiming that the lights will go out soon, whereas the other side (including some DG operators and large parks of the general public) claiming that there is nothing to worry about and that its all a conspiracy of the large production companies that want to protect their own interests and keep the electricity price high. The authors are of the strong opinion that this is NOT the way one should approach such an important subject as the integration of new, more environmentally friendly, sources of energy in the power grid. With this book the authors aim to bring some clarity to the debate allowing all stakeholders together to move to a solution. This book will introduce systematic and transparent methods for quantifying the impact of DG on the power grid.

Ajay Singh Particle Swarm Optimization Approach for Distributed Generation Planning to Improve the Voltage Profile Margin


Master's Thesis from the year 2017 in the subject Engineering - Mechanical Engineering, grade: 4.00, Kathmandu University (School of Engineering), course: Planning and Operation of Energy System, language: English, abstract: In power system, research area is widening and one is Distributed Generation (DG) integration in a distribution system. It restructures the power system and also helps in distribution system planning. This dissertation addresses the issue of voltage margin improvement by integrating DG unit and, therefore, this dissertation presents the model to enhance the candidate bus voltage of distribution system by optimal integration of DG units. The technical analysis is performed for radial distribution system (RDS).The proposed algorithm evaluates the base condition of loss and bus voltage and then generate populations of solutions at first stage. Optimization of DG unit size and locate the optimal bus can be done with the particle swarm optimization (PSO) method. The proposed paradigm works with the objective that minimize the active power loss under a constraint of voltage limit and DG size limit.Finally, the conclusion is that DG unit can locate optimally with optimized size to the distribution system for the voltage profile improvement of the buses and also the total loss of system is reduced. It is also concluded that the model can be used for any radial distribution systems.

Karimi Mazaher, Mokhlis Hazlie Under-Frequency Load Shedding Scheme for Islanded Distribution Network


Abnormal conditions such as overload and generator tripping usually result in large excursion of power system frequency, voltage and other system variables. In this case, an effective method to prevent the electric power system from instability, frequency collapse and blackout is an under-frequency load shedding scheme. It is applied in order to maintain stability of the system, when the power system generation fails to supply the increase of load. Load shedding is a common technique to maintain the power system stability by curtailment of partial load in some part of the system. However, the load shedding techniques for an islanded distribution network should be treated differently from the transmission power system. A particular approach of under-frequency load shedding scheme is required for an islanded system which is known to be not as strong as the grid.

El Bakari Khalil Smart Power Systems and Markets with Virtual Plants


Future distribution networks are expected to host high concentrations of distributed energy resources (DER) which include distributed generation, renewable energy sources, local storage systems and flexible loads. This book introduces a DER aggregation system (DERAS) that incorporates DER in the power system in an efficient and cost-effective manner. DERAS is developed based on the concept of the virtual power plant to facilitate the collective participation of the DER owners in the wholesale electricity market. The commercial interests of its stakeholders are incorporated in a trade subsystem that employs artificial neural networks to forecast the contribution of the aggregated DER population. Moreover, through the balancing and network support subsystems DERAS helps system and network operators to postpone or prevent excessive expenditures needed for network expansions or reinforcements. This book involves Systems Engineering to develop a scalable DERAS that fits in either competitively unbundled or traditionally consolidated electricity markets. Moreover, it presents an active network planning method that facilitates the development of Smart Grids.

Pieter Schavemaker Electrical Power System Essentials


The electrical power supply is about to change; future generation will increasingly take place in and near local neighborhoods with diminishing reliance on distant power plants. The existing grid is not adapted for this purpose as it is largely a remnant from the 20th century. Can the grid be transformed into an intelligent and flexible grid that is future proof? This revised edition of Electrical Power System Essentials contains not only an accessible, broad and up-to-date overview of alternating current (AC) power systems, but also end-of-chapter exercises in every chapter, aiding readers in their understanding of the material introduced. With an original approach the book covers the generation of electric energy from thermal power plants as from renewable energy sources and treats the incorporation of power electronic devices and FACTS. Throughout there are examples and case studies that back up the theory or techniques presented. The authors set out information on mathematical modelling and equations in appendices rather than integrated in the main text. This unique approach distinguishes it from other text books on Electrical Power Systems and makes the resource highly accessible for undergraduate students and readers without a technical background directly related to power engineering. After laying out the basics for a steady-state analysis of the three-phase power system, the book examines: generation, transmission, distribution, and utilization of electric energy wind energy, solar energy and hydro power power system protection and circuit breakers power system control and operation the organization of electricity markets and the changes currently taking place system blackouts future developments in power systems, HVDC connections and smart grids The book is supplemented by a companion website from which teaching materials can be downloaded.

Enam Khan Distributed Topology Inference of Distribution Networks using the RBTS


Reliability of power system depends on the up to date knowledge of the system state for operation and control. Shifting from large conventional production units to small and/ or renewable DG connected in the distribution network means more control and monitoring system require for the Distributed System operator caused by active generation and reactive power consumption by DG. It is technically impossible to continuously model the distribution grid in real time because of tremendous number of nodes distribution and elements system.Therefore it is interesting to explore concepts in fast and scalable topology processors for monitoring and controlling applications such as state estimation, OPF and static and dynamic stability assessment in electrical distribution network the need is evident to validate with meshed network to analyze the overall performance of the proposed methodology Decentralized Topology Inference of Electrical Distribution Networks. The topology inference processor is require minimal prior knowledge of electrical network structure by taking a series of time-stamped process measurements from each bays of each substation in the network and determine the topology.

Lesha Virtyt The stability analysis of the hydro-power plant


In this study we have addressed the problems that have to do with the running of the power system and the optimization of generation. We have treated the control of active and reactive power in order to keep the system stable condition. The objective of the control strategy is to generate and transmit power to a system composed of interconnection lines, in the most economical and safe methodology possible, keeping the voltage and frequency within norms. Also we gave the results of the simulation via Matlab of the dependency of the generator's electric parameters of an aggregate in the Vau-Dejes hydropower-plant versus the temperature of winding and oil of a power transformer of this aggregate.

Akhil Gupta Solar Photovoltaics Engineering. A Power Quality Analysis Using Matlab Simulation Case Studies


The solar Photovoltaic (PV) technology is gaining significant levels and is going to contribute a major share of total generated electricity in the coming years. PV technology is becoming a promising alternative source for fossil fuels. However, Power Quality (PQ) is the major concern that occurs between the grid and an end user. Any typical electrical distribution system exhibits a passive characteristic with respect to power flows when power flows from a substation to load. However, with inclusion of solar PV generators, this behaviour tends to be changed. The main characteristics related to PQ, such as voltage level, frequency, power factor and Total Harmonic Distortion (THD), may be affected.This book presents the analysis of PQ with the integration of grid-connected PV systems as distributed generation. The role of Maximum Power Point Tracking (MPPT) technique is investigated through implementing few basic MPPT techniques. Using the Matlab-simulation platform, the analysis of PQ is demonstrated. This analysis is based on real measurements of THD, Voltage levels, Current levels, DC voltage levels, real power and reactive power flows.

Syed Meer Kulam Ali I.,Raja K. and Tamilvani P. MPPT Based Wind Energy Conversion System


In this book shows a novel control approach of a three phase grid connected wind energy conversion system, incorporating a maximum power point tracker for dynamic active power generation jointly with reactive power compensation of distribution utility systems has been presented. Thus the five level multilevel inverter topology were chosen based on what has gone before, even if that topology may not be the best choice for the application. Several multilevel voltage source inverters and their modulation topologies are introduced. The cascaded-inverter with separated dc sources is discussed in detail with results to verify the proposed concepts. The improved capabilities of the grid-connected WECS to rapidly exchange active power with the electric system, simultaneously and independently of the reactive power exchange, permit to greatly enhance the operation and control of the electric system.

Dr. Md. Faruk Hossain AUTOMATIC GENERATION CONTROL IN ELECTRICAL POWER SYSTEM


Today a power system interruption is far more serious, work is interrupted, and modern domestic heating plants cease operating, the processing material is damaged, transportation is impaired and normal life of whole communities is disrupted. This greater dependence on a continuous supply of electrical energy has developed with the ability to build a high degree of reliability into the system. System disturbances caused by the load fluctuations result in changes to the desired frequency value. Automatic Generation Control (AGC), is very important issue in power system operation and control for supplying sufficient and both good quality and reliable electric power. This work deals with the AGC of Electrical (single and multi-area) power systems by using fuzzy logic controller (FLC). Three intelligent AGC controllers have been developed to regulate the power output and system frequency by controlling the speed of the generator with the help of fuel rack position control. The first one is fuzzy based gain scheduler (FGS), the second one is Fuzzy based proportional integral controller (FPIC), and last one is Fuzzy frequency controller (FFC).
