Performance Evaluation of Microgrid Management System by using a Hareware- In-Loop-Simulation Method

Abstract

This paper presents a real time digital simulator based test system as a new method for testing microgrid management system (MMS). This system is composed of a real time digital simulator and a developed communication emulator. Real time digital simulator runs a simulation case for microgrid model and distributed generation source model. Communication module emulates communication functions of micro-sources in microgrid by transmitting the simulated signals to MMS. The MMS controls operation of micro-sources to control the power flow at the point of common coupling (PCC) and the voltage and frequency of microgrid. A prototype MMS was tested for stand-alone and grid-connected operation to verify the validation of the developed hardware-in-the-loop simulation (HILS) system.

“…The distributed power generation refers to the use of various available energy sources, including renewable energy (solar, biomass, small wind, small water, wave energy etc.) and locally accessible fossil fuels (mainly natural gas) for power generation technology [1, 2]. The combination of DG units with loads and energy storage systems brings evolutionary changes to the traditional electric utilities and located close to the load being served [3, 4].…”
