Capacity configuration method for energy storage participating in peak regulation based on double-layer model

Abstract

The invention discloses a capacity configuration method, device and equipment for energy storage participating in peak regulation based on a double-layer model and a computer readable storage medium.The method comprises the steps of: constructing a first-layer optimization objective function with the maximum net income in the whole life cycle of an energy storage system as the objective, and setting constraint conditions; constructing a second-layer optimization objective function by taking the minimum sum of the per-unit value of the wind curtailment electric quantity in the scheduling day and the per-unit value of the net load peak-valley standard deviation as an objective; constraining the first-layer optimization objective function by using a constraint condition, and obtaining a corresponding to-be-selected configuration scheme according to the first-layer optimization objective function; and screening the plurality of to-be-selected configuration schemes according to the second-layer optimization objective function, and determining an optimal configuration scheme of the energy storage system. According to the technical scheme, when the energy storage system participates in peak shaving, a good peak shaving effect can be achieved, good net income can be obtained, and therefore the rationality and accuracy of energy storage system configuration are improved.

Description

technical field [0001] The present application relates to the technical field of energy storage configuration, and more specifically, relates to a capacity configuration method, device, equipment and computer-readable storage medium for energy storage participating in peak shaving based on a two-layer model. Background technique [0002] In the current energy Internet, how to improve energy utilization and promote the consumption of renewable energy is a current research hotspot. Taking wind power as an example, with the continuous increase in the penetration rate of renewable energy such as wind power, the economic problems caused by wind curtailment are still relatively serious. In order to solve the above peak shaving problem, it is necessary to give full play to the peak shaving capability of the thermal power unit, but making the unit enter the deep peak shaving stage or even the start-stop peak shaving stage will increase the operating loss of the unit and reduce its e...

AI Technical Summary

Problems solved by technology

[0003] Configuring energy storage systems in wind power high-permeability grids can effectively improve grid peak regulation pressure and increase grid wind power capacity, but the configuration of energy storage systems affects the effect of energy storage participating in peak regulation and its economy, so it is necessary to design energy storage reasonably The configuration strategy of system operation makes it take into account both peak shaving technology and economy

However, the current research on energy storage configuration does not take into account the optimization of energy storage charging and discharging power and the net income in the whole life cycle, therefore, it will reduce the rationality and accuracy of energy storage system configuration
