Abstract

The invention discloses a distributed wind-solar-storage integrated microgrid intelligent control system, which comprises a distributed generation unit, a distributed energy storage unit, a flexible load unit, a control unit and a network communication unit. The monitoring platform receives the flexible load unit through the network communication unit, the signals collected by the distributed energy storage unit and the distributed power generation unit, On the one hand, the monitoring platform stores the received acquisition signals in the database server, on the other hand, the received acquisition signals are fused and processed, and then send control commands to the flexible load unit, the distributed energy storage unit and the distributed power generation unit through the network communication unit after the processing; The monitoring platform displays the processing results on the display screen, and communicates with the workstation in two directions for engineers to control the monitoring platform, and the monitoring platform communicates with the mobile terminal in two directions through the Internet. Through reasonable optimization and dispatching, the utilization rate of clean energy and absorbing capacity are improved, so as to to achieve the optimal power matching of micro-grid system, to achieve efficient energy conservation.

Description

technical field [0001] The invention belongs to a micro-grid control system, and in particular relates to an intelligent control system for a distributed wind-solar-storage-integrated micro-grid. Background technique [0002] Distributed power generation mainly includes various renewable energy power generation. Its clean and environmentally friendly characteristics meet the requirements of low-carbon economic development. The power grid has brought a certain impact, which not only makes the power flow and fault mechanism characteristics of the power grid more complicated, but also due to its poor anti-disturbance ability, the light abandonment phenomenon is very serious, resulting in a decrease in the annual utilization hours of distributed power generation, which affects distributed power generation. Economics of investment. [0003] A microgrid is a small power system composed of distributed power sources, energy conversion devices, loads, monitoring and protection devic...
