Title:
ENERGY STORAGE CAPACITY OPTIMIZATION CONFIGURATION METHOD FOR IMPROVING RELIABILITY OF POWER DISTRIBUTION NETWORK
Document Type and Number:
WIPO Patent Application WO/2023/060815
Kind Code:
A1
Abstract:
An energy storage capacity optimization configuration method for improving the reliability of a power distribution network. The method comprises the following steps: (1) defining an "income-input ratio" of an energy storage system, wherein in formula (I), Ctotal is the construction cost of the energy storage system, f1 is an economic income of configuring the energy storage system, and f2 is a reliable income of configuring the energy storage system; (2) selecting a power interval of the energy storage system, and selecting a capacity interval according to the power interval of the energy storage system; (3) estimating "income-input ratios" of the energy storage system when configured with different capacities in a power supply network; and (4) searching for the optimal configured capacity of the energy storage system according to the "income-input ratio" of the energy storage system under the current capacity, that is, the configured capacity under the maximum "income-input ratio" of the energy storage system is the optimal configured capacity of the energy storage system. By means of the present invention, the configuration of energy storage power and capacity can be intelligently and efficiently planned, thereby realizing the comprehensive optimization of a reliable income and an economic income of an energy storage configuration; and the present invention has the advantage of a high degree of intelligence.
