The proportion of DC power generation, transmission, and distribution in power systems is continuously increasing. Currently, fault protection in DC power systems is an attractive yet difficult research topic. In this paper, a DC solid-state current limiter with adaptive current-limiting ability is proposed. The basic topology and the working principle of the proposed current limiter are presented...Show More
This paper proposes an optimal power flow scheduling strategy for the energy management of multi-MG systems. At the multi-MG level, the global central controller (GCC) is responsible for managing the MGs. The GCC calculates the amount of power exchanged within the MGs by using a novel optimal energy allocation policy. Based on the energy supply and demand mismatch, MGs are classified as providers ...Show More
Aiming at the problem that the output voltage of the photovoltaic (PV) array is much lower than the voltage required by the grid-connected inverter in the grid-connected power generation system, a new type of second order boost converter with high-gain and low switching tube voltage stress is proposed. The proposed topology is based on the basic Boost circuit, including three switching capacitors ...Show More
