Abstract

The invention discloses a comprehensive energy cluster coordination control method for improving the stability of a power grid. The method comprises: an anti-interference state observation method forimproving system stability, a measurement-correlation-prediction MCP modeling and evaluation method, a source network load comprehensive energy cluster coordination rapid response anti-interference control method and an optimization simulation platform, and a multi-benefit subject optimization operation and transaction risk hedging strategy based on dynamic game. According to the invention, basedon complex system theoretical analysis, a universal anti-interference state observer with engineering use value and an MCP modeling evaluation method are provided, the method can be used for a multi-time-scale cold / heat / electricity comprehensive energy coupling system in county urban and rural overall planning areas, a multi-energy power generation coordination optimization control method based oncloud interaction and an energy transaction simulation technology oriented to cluster benefit optimization can be provided for wide-area multi-energy power generation clusters such as photovoltaic / wind power / thermal power generation / gas turbines and the like, and a matched edge computing sensor and an intelligent controller are developed.

Description

technical field [0001] The invention belongs to the technical field of energy system management, power consumption efficiency, and comprehensive energy optimization and control, and specifically relates to a coordinated control method for comprehensive energy clusters that improves the stability of power grids. Background technique [0002] As the generator sets in the power grid continue to move towards the direction of large capacity and high parameters, and the degree of automation is getting higher and higher, higher requirements are put forward for the frequency regulation control of the power grid in the wide area energy Internet. All aspects of the smart grid system have gradually matured. It is necessary to carry out solid theoretical research and demonstration verification for large-scale smart grid systems to participate in power frequency regulation. In the following aspects: one is based on the background of large-scale grid-connected renewable energy such as win...
