Abstract :
Microgrid (MG) is composed of loads, Micro-Sources (MS) and Energy Storage Systems (ESS) operating as a single controllable system. In MGs, with high levels of Distributed Energy Resources, the stability becomes an important issue. The concept of “base-load” might not be considered in a typical MG, i.e., large load variations are expected to occur. Furthermore, different load conditions are effective on MG stability. In this paper, a typical MG is modeled completely and eigenvalues of the system are extracted based on small signal analysis in state equations. Thereafter, different load conditions are investigated and critical conditions of the loads are obtained.
