AC/DC hybrid microgrid collaborative protection coordination control system

Abstract

The invention discloses an AC / DC hybrid microgrid collaborative protection coordination control system, and belongs to the technical field of power generation and power supply. A part of power generated by each pumped storage power station is stored in an energy storage battery pack, and the power storage capacity is used for controlling the power generation efficiency, so that the power supply stability of each pumped storage power station is high. The system comprises a wireless module, a memory, an energy storage control monitoring platform, a power supply network, a plurality of power utilization units connected to the power supply network and a plurality of pumped storage power stations arranged in different positions and provided with controllers, and further comprises a power storage capacity based power generation efficiency control strategy module; and each pumped storage power station transmits the power generated by the corresponding pumped storage power station to the powersupply network through a grid-connected device independently. The power storage capacity based power generation efficiency control strategy module, the wireless module and the memory are connected with the controllers; and the controllers are connected with the energy storage control monitoring platform through the wireless module.

Description

technical field [0001] The invention relates to the technical field of power generation and power supply, in particular to an AC / DC hybrid micro-grid coordinated protection cooperation control system. Background technique [0002] At present, the electricity generated by the pumped storage power station is generally directly transmitted to the power supply network, and the stored power is not used to control the power generation efficiency, resulting in poor power supply stability of the pumped storage power station. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the electricity generated by the existing pumped storage power station is usually directly transmitted to the power supply network through the grid-connected device, and the stored power is not used to control the power generation efficiency, resulting in pumped storage Insufficient power supply stability of the power station is poor, providing a reliable way t...
