Description

technical field [0001] The invention relates to the technical field of peak-shaving management and control of an AC-DC distribution network in a power system, and specifically relates to a method and system for managing and controlling peak-shaving operation of a distribution network in a multi-subject interactive game. Background technique [0002] At present, in terms of distribution network peak-shaving management and control technology, most studies only consider improving the distribution network's own peak-shaving capability. Peak shaving control, but relying on the distribution network itself to participate in peak regulation increases the operating cost and construction cost of the distribution network, which is not conducive to the long-term development of the power grid. Therefore, the development of other entities with energy storage properties in the power grid, such as electric vehicles and energy storage devices to participate in peak regulation, can not only r...

Problems solved by technology

However, the current research is all about peak regulation on a single network or feeder, and fails to consider the power support between multiple networks or feeders

Since the AC and DC distribution network has controllable power electronic components such as converters, it has the advantages of controllable power flow and no harmonics, and is widely used. Research on peak shaving control technology for AC and DC power distribution network considering power support between multiple networks or feeders
