Control devices development of residential single-phase PV-ESS microgrid

With the fast proliferation of residential microgrids integrated into the power grid, it is crucial to develop a low cost and high efficiency microgrid central control (MGCC) for promoting the large-scale application of residential microgrids. Considering various users' demand, we develop a novel MGCC based on the multi-level communication model. The MGCC integrates many functional modules, including black start, seamless transfer, power prediction, operation optimization control, and energy management. The experiment based on the CETLAB microgrid platform verifies the proposed MGCC and strategies. The control device development of the residential microgrids with the photovoltaic and energy storage system (PV-ESS), promotes the smart grid construction, electric power market reform, and national energy policy.
