Distributed Power Systems for Enhancing the Resilience, Reliability, Security, and Economics of Electricity Grid

Abstract

Microgrids in distributed power systems represent a small-scale version of centralized electricity grid, which are es-tablished in load centers like universities, hospitals, airports, military bases, and residential areas for enhancing the resilience, reliability, security, and economics of distributed power systems. Networked microgrids in distributed power systems provide a robust control of integrated renewable resources and battery storage in energy-constrained communities and allow custom-er participations in the operation of critical infrastructures.With the increasing penetration of distributed energy resources and the proliferation of microgrids, transactive energy is considered as an enabler of end-to-end energy trading and coordi-nated operations among microgrids for lowering the energy costs in power distribution systems. However, transactive energy trading poses new operation challenges, which are managed by distribution system operators (DSOs) as networked microgrids interact with power distribution systems. The role of networked microgrid in distribution system operation is discussed in this presentation. The presentation discusses a bi-level framework to conceive an optimal trading strategy in the hierarchical oper-ation of DSOs. The upper level operation considers a transactive energy market where networked microgrids participate to trade energy locally. The trading results are submitted to the lower level in which the DSO optimizes the distribution power flow and the distribution network reconfiguration. The proposed solution enables transactive energy trading decisions by net-worked microgrids and effective distributed energy market clearing by DSO. Case studies show the applications of the pro-posed framework and algorithm in the power distribution system operation.
