Method for conservative calculation of short-term abandoned wind power of generating-limited wind power plant

Abstract

The invention relates to a method for conservative calculation of short-term abandoned wind power of a generating-limited wind power plant, and belongs to the technical field of operation and control of a power system. First of all, historical short-term prediction data of the wind power plant in a past year and historical actual active power data under a generating-limited condition are counted, then, a relation between the historical short-term prediction data and the historical actual active power data under the generating-limited condition is obtained, accordingly, the short-term abandoned wind power of the generating-limited wind power plant is conservatively calculated, and the historical short-term prediction data and the historical actual active power data under the generating-limited condition are updated. The method provided by the invention solves the problem of a conventional power system in calculating the abandoned wind power of a generating-limited wind power plant and provides a basis for high-energy-consumption enterprises in participation of consumption of new energy.

Description

technical field [0001] The invention relates to a method for conservatively calculating the short-term wind curtailment of wind farms with limited power generation, and belongs to the technical field of power system operation and control. Background technique [0002] In recent years, with the continuous growth of new energy installed capacity and the construction of new energy power generation bases, serious problems of wind and light abandonment have emerged in Gansu and other regions with rich installed capacity of new energy power generation. The main cause of this problem is insufficient spinning reserve in the power system caused by insufficient local load. Due to the support of national policies, high-energy-carrying industrial parks have been built in Gansu and other areas with rich installed capacity of new energy power generation. A large amount of electric energy is used in the production process, and the equipment has a certain ability to adjust its own power loa...

Problems solved by technology

However, because wind farms in Gansu have been in a state of severe power-restriction production for a long time, there is a large deviation between the actual output power of the wind farm and the actual power that can be generated by the wind farm, and the short-term predicted power of wind power cannot truly reflect the actual output power of the wind farm. Actual output power

Therefore, when the high-energy-carrying industry participates in power system dispatching, it is difficult for the power system to accurately predict the short-term wind power that can be generated by the wind farm, so that it is impossible to calculate the short-term limited wind power of the wind farm
