Designing and simulation of a DC microgrid in PSCAD

DC and AC-DC hybrid microgrids are evolving technologies used in telecommunication industry concerning its reliability, safety and efficiency in supplying power. This paper presents a DC Microgrid system designed for telecommunication power supply system, and three possible modes of operations are discussed. The DC microgrid comprises of a solar PV array as the distributed energy source, a battery bank as the energy storage element and the utility grid. The solar characteristics are verified using manufacture specification. The irradiance data used for solar PV is actual data, which was measured in a typical sunny day. A proper Energy Management and Control is proposed for the reliable operation of the DC microgrid. The simulated results show that the energy management and control works as expected.
