Description

technical field [0001] The invention relates to an optimization control method, in particular to an active distribution network coordination optimization control method considering ZIP load. Background technique [0002] For the traditional distribution network, due to the lack of active power inside, when studying its operation optimization, active power optimization cannot be carried out, but reactive power optimization is only required. With the continuous growth of power demand and the shortage of conventional energy sources, various distributed generation (DG, Distributed Generation) have begun to connect to the distribution network on a large scale, followed by a large number of energy storage and new controllable equipment in the distribution network. Wide application in the grid. The traditional passive unidirectional power supply distribution network is gradually transforming into a multi-source bidirectional power supply distribution network. Faced with a series o...
