要約(英語): As is known, solar power generation and wind power generation are undoubtedly the most promising renewable energy power generation technologies, while they have a lot of problems when they are connected to the power grid. In order to solve the negative impact of them in the microgrid, this paper proposes a method which divides the power system load into multiple levels, and implements a hierarchical load shedding scheme for the microgrid according to different operation conditions of the microgrid. Different from the previous load shedding schemes, this scheme regards some household appliances as the first removable loads, and some others as the second or the third removable loads. As a result, better protection for electrical energy of critical loads can be realised. Moreover, load shedding can be performed step by step, which ensure power supply of some important loads such as lighting, communications. What's more, the method is simulated and analyzed based on the PSIM software.
