Abstract

The invention discloses a distributed power supply cluster control system, comprising: a distributed power supply cluster monitoring master station and multiple distributed power supply clusters, each distributed power supply cluster includes: a distributed power supply cluster monitoring master station A distributed power cluster management and control device and multiple distributed power sources connected to the distributed power cluster management and control device. The invention also discloses a control method of the distributed power cluster control system: the distributed power cluster monitoring master station monitors the operating status of the power grid in real time, performs regional optimal power flow calculations, and obtains the active power of each distributed power supply group under the optimal power flow condition Power control setting value, reactive power control setting value, power factor numerical control setting value and voltage control setting value, and send the control setting value of the distributed power supply cluster to the distributed power supply cluster management and control device, and the distributed power supply cluster management and control device Perform distributed power control. The invention can reduce the impact of distributed power grid connection on the security and stability of the grid.

Description

technical field [0001] The invention relates to a distributed power cluster control system, and also relates to a control method for the distributed power cluster control system, which belongs to the technical field of distributed power sources. Background technique [0002] The application of new clean energy such as photovoltaics and wind turbines is an important means to solve the future energy crisis and environmental pollution. According to the national development planning goals, my country's distributed power installed capacity can reach 74GW in 2015, accounting for 5.0% of the country's total installed capacity in the same period; in 2020, the distributed power installed capacity can reach 187GW, accounting for 9.3% of the country's total installed capacity in the same period. The grid-connection of high-penetration distributed power generation poses a challenge to the safe and reliable operation of the power grid. Therefore, increasing the proportion of new energy c...
