摘要
Abstract
Owing to the existence of numerous wind power plants with relatively small installed capacity in a wide area, some operators choose to delegate all or part of the wind power plants to their subordinate operators to dispatch while still operating in the same control area.In order to coordinate the operation of traditional units and wind power plants and accommodate wind energy as much as possible, a real-time coordinated control architecture for wind power with two-level dispatching in one and the same control area is introduced and put into production making wind power plants directly controlled by subordinate operators as overall virtual automatic generation control (AGC) units in the higher operator's control area.The higher operator calculates and updates the wind power output index of all virtual AGC units for subordinate operators every five minutes according to current power grid operation status.The ultra-short term load forecast, wind power actual output and wind power ultra-short term forecast, then the indices are sent to subordinate operators and executed by individual wind power plants.The actual operation in winter and heating period shows that the grid in Beijing-Tianjin-Tangshan region can accommodate more wind power using the proposed strategy.关键词
