Abstract

The invention provides an energy storage capacity and power planning method for auxiliary frequency modulation of a thermal power plant, and the method plans the construction of an auxiliary frequencymodulation energy storage system based on the historical operation big data of a unit; Therefore, the calculation speed of the system is accelerated, and the simulation calculation time is greatly shortened. The method comprises the following steps: step 1, based on a full life cycle theory managed by a thermal power plant, establishing a thermal power plant income model by considering the construction cost of an energy storage system in the full life cycle and the comprehensive income of assessment and compensation of the thermal power plant; step 2, setting an income calculation task of thethermal power plant according to a regional power grid operation rule; step 3, determining an approximate range where the optimal energy storage configuration is located by setting a larger simulation step length; step 4, creating a distributed cluster, and according to the characteristics of the distributed cluster, distributing a simulation calculation task, based on historical operation data of a thermal power plant AGC set, carrying out big data simulation on the PCS operation power and capacity with 0.1 MW and 0.1 MWh as small simulation step lengths, and finally summarizing a simulationresult and analyzing to obtain optimal energy storage configuration.

Description

technical field [0001] The invention relates to power system technology, in particular to an energy storage capacity and power planning method for auxiliary frequency regulation of thermal power plants proposed in the field of frequency regulation of power plants. Background technique [0002] With the global energy shortage and the deterioration of the climate environment, energy conservation and emission reduction, green energy and sustainable development have become the focus of attention of all countries at this stage. So more and more renewable energy is connected to the grid, but this also brings new problems to the traditional grid. In some cases, new energy does not have the inertial response characteristics of traditional power sources, and the output is fluctuating and uncertain. After large-scale new energy is connected to the grid, it will bring new pressure to the frequency regulation of the grid, so new assistance is urgently needed Frequency modulation is use...
