REAL TIME SIMULATION OF A DC MICROGRID WITH CONTROL SCHEMES FOR POWER MANAGEMENT AND VOLTAGE STABILIZATION

摘要

The concept of a DC Microgrid (DCMG) is a promising option to integrate various non-conventional energy resources in islanded and grid connected modes. The DCMG proposed in this work consists of renewable energy sources, battery energy storage system, and various loads. The control schemes, proposed by the authors in [1], [2], have been utilized for the power management and maintaining the DC grid voltage under different operating scenario, including fault conditions. Before physical installation of the DCMG, it is necessary to simulate it in the real time environment to evaluate its performance. This paper presents the testing, validation, and performance evaluation of the proposed DCMG on Real Time Digital Simulator (RTDS).
