Abstract

The invention belongs to the technical field of electric power system new energy, and particularly relates to an electric power system energy storage configuration calculation method based on new energy abandoned power, which aims at improving the utilization rate of new energy, combines actual operation data with prediction data, is not influenced by a power grid rack in calculation, does not involve an intelligent algorithm in the calculation process, and improves the energy utilization rate of the new energy. The practicability is high; according to the method, the new energy abandoned power curve is obtained by obtaining the calculation boundary condition, the energy storage configuration initial value is obtained based on the new energy abandoned power curve, the new energy utilization rate after energy storage configuration is calculated, and the power and energy of power grid configuration energy storage are obtained. The method is widely applied to the technical field of power system new energy.

Description

technical field [0001] The invention belongs to the technical field of new energy sources in electric power systems, and in particular relates to a method for calculating energy storage configurations of electric power systems based on abandoned electric power of new energy sources. Background technique [0002] The rapid growth of new energy is in line with the concept of green development, but the uncertainty of wind / light resources, the intermittency and volatility of new energy, and the disorder of new energy access have brought new challenges to the safe and stable operation of the power grid and the consumption of new energy. Here comes a serious challenge. [0003] Energy storage has the technical characteristics of quick response and two-way adjustment, and can match the output of new energy in real time. It is an important support for the development of new energy. It also has the technical advantages of strong environmental adaptability, small-scale decentralized c...
