Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0045] Such as Figure 1-3 As shown, the embodiment of the present invention provides a method for arranging energy storage power stations in multiple application scenarios, including:

[0046] Step 1. Preliminarily select the location near the line with voltage problems and power flow congestion as the first pre-selected energy storage access point; and when selecting the location near the voltage problem (voltage instability requires voltage regulation) and power flow congestion lines, you should first consider Consider the location of the near area of ​​the voltage problem, and then consider the location of the near area of ​​the power flow congested line; for example: under the operation mo...

Abstract

The invention discloses an energy storage power station arrangement method for multiple application scenarios. The method comprises the following steps: initially selecting a near zone of a voltage problem and a power flow congestion line as an energy storage access point; during energy storage and frequency modulation, selecting a point having the smallest influence on the power angle of the generator as an energy storage access point under the condition that the contact section of the regional interconnection system is weak; arranging only one energy storage power station at the same energystorage access point, and the capacity of the energy storage power station being the maximum capacity for solving a single problem; the access point of the energy storage power station taking economicoptimum as a target function, and taking the solution of the energy storage power station to the peak regulation problem, the voltage regulation problem, the frequency modulation problem and the tidecongestion problem of the power grid as constraint conditions, so as to construct an energy storage power station arrangement model; and solving the energy storage power station arrangement model toobtain the arrangement position and capacity configuration of the energy storage power station. According to the energy storage power station arrangement obtained through the method, calculation is simpler, the capacity of the energy storage power station can be more effectively utilized to solve various problems, and economic benefits are better.

Description

technical field [0001] The invention relates to the field of power system analysis, in particular to a method for arranging energy storage power stations with multiple application scenarios. Background technique [0002] Nowadays, more and more renewable energy is connected to the power grid. The randomness and volatility of renewable energy output have brought impact to the power system and brought more problems to the power grid. Since the energy storage power station has multiple functions such as voltage regulation, evacuation, frequency regulation and peak regulation, it has a positive effect on the safe and stable operation of the power grid. Therefore, building an energy storage power station has become a method to enhance the stability of the power grid. However, how to arrange energy storage power stations so that energy storage power stations can solve more grid problems and obtain greater economic benefits is still not well resolved.
