Available in PDF, EPUB and Kindle. Book excerpt: Energy management system (EMS) is an important component of smart grid operation. A proper EMS is the key to the integration of smart grid (SG) features, which include two-way communication, smart metering as well advanced control algorithms, in order to operate different components of SG efficiently and constructively. EMSs are both applied on the entity's and the system's level. On the entity level, individual entities don't coordinate with the system operator to optimize the objectives globally which would lead to inefficient solutions. System level EMS is implemented using centralized and decentralized approaches. Some of crucial drawbacks of the centralized EMS approach are that it's incapable of considering customer preferences while optimizing the operation of the networks, in addition to the lack of flexibility and scalability. Nevertheless, in the decentralized EMS approach, the customers and the system operator share information and interact constructively in optimizing their objectives. However, this approach still requires central coordination and long back-forth process to converge, as there is no shared background of mathematical foundation. In addition to that, most of the proposed decentralized techniques, do not consider network constraints, especially for unbalanced systems. This thesis proposes a Zone-Distributed Optimization System (ZDOS) using distributed semi-definite programming for energy management of a SG. ZDOS divides distribution systems into numerous micro grid-like regions, or zones, to facilitate smart grid operation. The proposed ZDOS divides the grid into a number of Zone-Specific Optimization Subsystem (ZSOS), each responsible for controlling and managing the activities inside a zone. The ZDOS clusters the distribution system based on the customer-class (residential, commercial and industrial). Each class is controlled by ZSOS in order to optimize a certain objective function, as well as a set of constraints which are consistent with customer's nature, preferences, requirements and the applied Demand Response (DR) strategy. Furthermore, ZSOS's of connected zones exchange local information at the point of connectivity indicating the desired power exchange and voltage level until the iterative process of every ZSOS is satisfied. Simulations and analysis are conducted on a modified 123-IEEE test system, which include diesel generators, renewable energy resources, and energy storage systems. The system is tested under different scenarios and demand response strategies. The analysis has shown that the results obtained by ZDOS are valid as the supply and demand are always balanced. Furthermore, the performance of ZDOS for minimizing operational costs has significantly improved when applying the DR, compared to ZDOS results without DR. The effectiveness of a multi-objective ZDOS when taking into consideration the preferences and requirements of different customers has been proven.

Download or read book A Distributed Optimization Method for Optimal Energy Management in Smart Grid written by Dinh Hoa Nguyen and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter presents a distributed optimization method named sequential distributed consensus-based ADMM for solving nonlinear constrained convex optimization problems arising in smart grids in order to derive optimal energy management strategies. To develop such distributed optimization method, multi-agent system and consensus theory are employed. Next, two smart grid problems are investigated and solved by the proposed distributed algorithm. The first problem is called the dynamic social welfare maximization problem where the objective is to simultaneously minimize the generation costs of conventional power plants and maximize the satisfaction of consumers. In this case, there are renewable energy sources connected to the grid, but energy storage systems are not considered. On the other hand, in the second problem, plug-in electric vehicles are served as energy storage systems, and their charging or discharging profiles are optimized to minimize the overall system operation cost. It is then shown that the proposed distributed optimization algorithm gives an efficient way of energy management for both problems above. Simulation results are provided to illustrate the proposed theoretical approach.

This book was released on 2023-01-25 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to work out the distributed economic operation in smart grids in a systematic way, which ranges from model-based to model-free perspectives. The main contributions of this book can be summarized into three folds. First, we investigate the fundamental economic operation problems in smart grids from model-based perspective. Specifically, these problems can be modeled as deterministic optimization models, and we propose some distributed optimization algorithms by integrating the multi-agent consensus theory and optimization techniques to achieve the distributed coordination of various generation units and loads. Second, due to the randomness of the large-scale renewable energies and the flexibility of the loads, we further address these economic operation problems from a model-free perspective, and we propose learning-based approaches to address the uncertainty and randomness. At last, we extend the idea of model-based and model-free algorithms to plug-in electric vehicles (PEVs) charging/discharging scheduling problem, the key challenge of which involves multiple objectives simultaneously while the behavior of PEVs and the electricity price are intrinsically random. This book presents several recent theoretical findings on distributed economic operation in smart grids from model-based and model-free perspectives. By systematically integrating novel ideas, fresh insights, and rigorous results, this book provides a base for further theoretical research on distributed economic operation in smart grids. It can be a reference for graduates and researchers to study the operation and management in smart grids. Some prerequisites for reading this book include optimization theory, matrix theory, game theory, reinforcement learning, etc.

It shows the reader how reliable control can be achieved so as to realize the potential of small networks of diverse energy sources, either singly or in coordination, for meeting concerns of energy cost, energy security and environmental protection. The book demonstrates how such microgrids, interconnecting groups of generating units and loads within a local area, can be an effective means of balancing electrical supply and demand. It takes advantage of the ability to connect and disconnect microgrids from the main body of the power grid to give flexibility in response to special events, planned or unplanned. In order to capture the main opportunities for expanding the power grid and to present the plethora of associated open problems in control theory Control and Optimization of Distributed Generation Systems is organized to treat three key themes, namely: system architecture and integration; modelling and analysis; and communications and control. Each chapter makes use of examples and simulations and appropriate problems to help the reader study. Tools helpful to the reader in accessing the mathematical analysis presented within the main body of the book are given in an appendix. Control and Optimization of Distributed Generation Systems will enable readers new to the field of distributed power generation and networked control, whether experienced academic migrating from another field or graduate student beginning a research career, to familiarize themselves with the important points of the control and regulation of microgrids. It will also be useful for practising power engineers wishing to keep abreast of changes in power grids necessitated by the diversification of generating methods.
