Clean energy power grid 'source load domain' coordination regulating method

Abstract

The invention discloses a clean energy power grid 'source load domain' coordination regulating method, and belongs to the field of electric system operation and control. The clean energy power grid 'source load domain' coordination regulating method fully considers power grid balance adjustment demands, multi-source margin adjustment characteristics, interactive load regulation characteristics, multi-source regulation cost characteristics, clean energy consumption maximization and other factors, defines a multi-control domain scheduling mode, introduces a decision coefficient vector of a normal control domain, exception control domain and emergency control domain, through the control priority of each domain, a source load domain coordination regulating optimization model is established, and satisfies system abundant demands with the minimum regulating quantity to achieve maximum clean energy consumption. According to the clean energy power grid 'source load domain' coordination regulating method, a running new method of multi-domain control is introduced, the multi-source and multi-load regulating characteristics are completely involved, a multi-source and multi-load decision strategy is fully optimized, system adjustment margin, clean energy consumption and regulation cost amount and other factors are integrated to achieve the overall optimization of system resource regulating.

Description

technical field [0001] The invention belongs to the field of power system operation and control, and in particular relates to a method for coordinating and regulating the "source-load domain" of a clean energy grid. Background technique [0002] In the safe and stable operation of the power grid, the grid balance adjustment margin is one of the core factors. Multi-source, multi-load and multi-domain multi-source include conventional power sources: hydropower and thermal power; clean energy: photovoltaic, wind power and nuclear power; energy storage: battery energy storage, centralized heat storage and distributed heat storage; Including: refrigeration, air conditioning, irrigation and heating load; multi-domain means that the power grid is in the normal regulation stage, called the normal regulation domain, the power grid has no normal regulation ability, and is in the abnormal regulation stage, called the abnormal regulation region, and the power grid loses the regulation a...
