An Adaptive Control Strategy for Remotely Located Microgrid Comprised of Solar PV-Battery Storage-Synchronous Generator Based DG Set

In this paper, a modified leaky-least mean square (MLLMS) control strategy for remotely located microgrid includes solar photovoltaic (PV), battery storage (BS) and diesel generator (DG) set is developed to provide continuous supply to remote locations. The storage battery is integrated at the DC link with the help of a bidirectional buck-boost converter (BDC). It functions as a buck converter during the charging of the battery. Whereas it operates as a boost converter when it discharges power. Moreover, the BDC fixes PV maximum power point (MPP) voltage at the DC link; thereby, peak power is harvested. Here, a synchronous generator based DG set is connected at the point of common interphase (PCI) to provide the load demand. It feeds linear or nonlinear loads. The linear and nonlinear loads demand reactive power and harmonics; thus, the voltage source converter (VSC) that integrates the energy sources at the PCI is controlled to compensate for power quality (PQ) issues.
