Embodiment Construction
[0083] The present invention considers the micro-grid real-time voltage control method of the reactive power output balance degree of the micro-power supply, which specifically includes the following steps:
[0084] Step 1: For different types of micro-power sources, a general model of the upper limit of reactive power output of micro-power sources under different working conditions is established, including the following steps:
[0085] Step 1.1: Analysis of the operating characteristics of the micropower supply. According to the grid-connected form of the micro-power source in the micro-grid, it is divided into a direct grid-connected micro-power source and an inverter-interfaced micro-power source. The former mainly includes diesel generators and large grid equivalent power sources connected to the point of public coupling (PCC point). Those mainly include micro-gas turbines, fuel cells, wind turbines, photovoltaics and other micro-power sources, as well as batteries and s...
