Coordination of Distributed Energy Resources in Microgrids: Optimisation, control, and hardware-in-the-loop validation provides a structured overview of research into techniques for managing microgrids with distributed energy resources (DERs). The DERs including distributed generators, energy storage systems, and flexible loads are posing both challenges and opportunities to microgrids' security, planning, operation, and control. Advanced operation and control techniques are needed to coordinate these components in the microgrids and maintain power quality, as well as keeping the system economically feasible.
The distributed energy resource (DER) refers to the small-scale energy generation and storage units, as well as flexible loads. Microgrids are distribution systems with a group of interconnected loads and DERs within clearly defined electrical boundaries that act as a single controllable entity with respect to the main grid. A microgrid can connect and disconnect from the main grid to enable it to operate in both grid-connected and islanded modes. This book focuses on three research problems of the DERs in the microgrid: planning, operation, and control. The planning aims to determine the optimal size and site as well as investment plan of the DER units in the microgrid over a long-time horizon, e.g., 5 years to 20 years; The operation of the microgrid focuses on the operational dispatch horizon over a short-term time interval, e.g., from 5 minutes to a few hours or one day. The objective is to dispatch the DERs for optimal energy management and bus voltage regulation; The control of the microgrid is concerned on the real-time timescale, i.e., milliseconds to seconds, and the objective is to maintain the voltages and frequency within desired operational ranges, achieve power sharing and balancing among DERs and loads.
This book is for researchers and students in the area of smart grids, power engineering, and control engineering, as well as for advanced students, transmission network and grid operators. It focuses on cutting-edge techniques for secure, economic, and robust operation and control of microgrids. Effective coordination of DERs on both temporal and spatial scales are introduced in detail. Topics covered include comprehensive mathematical models of DERs and microgrids, sizing and siting of DERs under uncertainties, stochastic and robust optimisation for active and reactive power dispatch of DERs in microgrids, distributed coordinated control, and hardware-in-the-loop tests for validation of control algorithms.
