Management of Power in AC/DC Hybrid Microgrid and its Harmonic Analysis by using D-STATCOM

Babita Nanda ^[2] | K. Balasriram

Abstract: In the present scenario, the increasing penetration of solar energy can be significant challenge due to the variation of power generation. One of the solution to improve the quality of power supply and guarantee of system stability is energy storage system (ESS). In this project, a AC-DC hybrid micro grid is designed based on photovoltaic (PV), generator and energy storage system are coordinated control is proposed to manage the power according to the load demand With D-STATCOM and without D- STATCOM. Moreover, AC-DC buses are interconnected by the bidirectional converters. The power control of the interlinked converters is enabled when the AC or DC side suffer from the active power demand shortage. In particular, if the AC micro grid doesnt satisfy the reactive power demand, then the distributed static synchronous compensator (D-STATCOM) is used for the compensation. A DC-DC Boost converter is connected to boost out the input voltage from the photovoltaic (PV) farm which is given to DC-bus. The system is tested with a different load i. e. inductive, pulse, non-linear load connected to the AC-side. The proposed topology is verified by doing simulation of MATLAB R2016b for management of power between two AC and DC sides under normal conditions and fault conditions with high efficiency, reliability and robustness in islanding mode.
