TL;DR: In this paper, the cooperative control strategy of microsources and the energy storage system (ESS) during islanded operation is presented and evaluated by a simulation and experiment, where the ESS handles the frequency and the voltage as a primary control.

TL;DR: This paper presents power-control strategies of a grid-connected hybrid generation system with versatile power transfer, the combination of photovoltaic array, wind turbine, and battery storage via a common dc bus, and its control system.

TL;DR: In this paper, a simple circuit model of the solar array is used to easily simulate its inherent characteristics with the basic specification data, and detailed power and protection control of the GCPS as well as its electrical circuits have been represented by user-defined and built-in components to take into account transients in normal and fault conditions, which are dominated by its power electronic controller.

TL;DR: In this paper, a hardware in-the-loop simulation (HILS) system is proposed to develop and test control algorithms and operation strategies for a microgrid, which is composed of a real-time digital simulator (RTDS) for realtime simulation of the micro-grid, a prototype microgrid management system (MMS) under test, and a communication emulator for interface between the prototype MMS and the RTDS.

TL;DR: Simulation results show that the voltage and frequency deviations are reduced with the proposed coordinated control algorithm for distributed battery ESSs.
