The invention relates to a system and a method for enhancing wind power consumption. The output of a wind turbine converges through a wind power system AC bus. The wind power system AC bus is connected to a power grid through a wind power system transformer and a transmission line. A battery energy storage system converges through an energy storage and heat supply system AC bus. The energy storage and heat supply system AC bus is connected to the power grid through an energy storage and heat supply system transformer and the transmission line. A heat supply system is connected with the energy storage and heat supply system AC bus. According to the technical scheme provided by the invention, the problem that the regulation rate of a heat storage boiler does not match the rapid fluctuation of wind power is solved through fast response of the battery energy storage system. Through the electric energy bidirectional regulation ability of the battery energy storage system, multi-target operation of the combined system is realized, and wind power consumption is maximized.
Description
technical field [0001] The invention relates to the field of new energy power generation and energy storage, in particular to a system and method for improving wind power consumption. Background technique [0002] In recent years, my country's wind power installed capacity has continued to grow. As of the end of June 2016, the cumulative grid-connected capacity reached 137 million kilowatts. But it is accompanied by the continuous increase of wind power abandonment. In the first half of 2016, the wind power abandonment amounted to 32.3 billion kWh, resulting in a huge waste of clean energy. The contradiction between supply and demand between source and load in heating areas is more obvious, especially during the winter heating period, the peak shaving capacity of thermal power units used for grid peak shaving plummets, and the space for the grid to accept wind power is reduced, which further leads to a high proportion of wind curtailment, resulting in the average utilization...
