Abstract: A clustered energy-storing micro-grid system includes a renewable energy device, a clustered energy-storing device, an electrical power conversion device and a local controller. Before coordinating and allocating power to a plurality of loads, the clustered energy-storing device stores and releases the power in a centralized manner. This, coupled with the control exercised by the local controller over the electrical power conversion device, controls the micro-grid system in its entirety so that the micro-grid system operates in cost-efficient optimal conditions, under a predetermined system operation strategy, and in a system operation mode.

Abstract: A simulation test system of a cluster-based microgrid integrated with energy storages is characterized in that an operation simulation test of a physical microgrid system is conducted with a computer as well as a power generation data and a power consumption data which are imported. Hence, the user can verify the feasibility of applying various design concepts and ideas, such as controller parameter design and system energy management strategies, to a physical microgrid system, without installing or using any physical apparatuses.
