Energy storage capacity optimal configuration method based on production operation simulation

Abstract

The invention discloses an energy storage capacity optimal configuration method based on production operation simulation, and belongs to the technical field of electrical engineering. The energy storage capacity configuration method comprises the following steps: firstly, quantifying uncertain factors such as load, wind power and photovoltaic by adopting a Monte Carlo method, and generating a typical operation scene of a power system; furthermore, an energy storage capacity optimization configuration model based on production operation simulation is established, and the global optimality of the scheme in the planning level and the operation level is ensured by taking the construction cost, the operation cost, the new energy consumption level and the electric energy quality as optimization targets. And finally, comparing with the operation condition of a power system without energy storage, and measuring the comprehensive benefit of an energy storage configuration scheme through a new energy consumption index and a voltage quality index.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an energy storage capacity optimization configuration method based on production and operation simulation. Background technique [0002] The construction of a new power system with new energy as the main body is an important supporting means to achieve the strategic goal of "carbon peaking and carbon neutrality". However, with the widespread access of wind power and photovoltaics, their randomness and intermittency will bring severe challenges to system power balance, peak and frequency regulation, and voltage stability. Energy storage equipment has the ability to distribute energy across time and space. It can store electrical energy as a load when wind power and photovoltaics are in full swing, and can also output electrical energy as a power source during periods of low wind and photovoltaic output. Therefore, through the coordinated operation between energy st...
