Title:
COMPREHENSIVE EVALUATION METHOD AND APPARATUS FOR PERFORMANCE OF BATTERY ENERGY STORAGE SYSTEM, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/120115
Kind Code:
A1
Abstract:
Disclosed in the present invention are a comprehensive evaluation method and apparatus for performance of a battery energy storage system (BESS), and a computer device. According to the method, on the basis of a BESS capacity attenuation function, a daily operation cost total objective function, and a linearized power balance constraint condition, energy storage power constraint condition and control strategy constraint condition of the BESS, a comprehensive evaluation value of multiple different physical performance indexes of the BESS is calculated by utilizing a group-order relationship evaluation algorithm; under multiple different scheduling scenarios of combining a load side with an energy side and a upper grid side, the operation range of the state of charge of the BESS is controlled in real time on the basis of the control strategy constraint condition, and a BESS continuous charging and discharging time strategy is established according to different scheduling requirements; and six different physical performance index parameters of the BESS are iterated into the constraint conditions, and finally a comprehensive evaluation value of the six different physical performance indexes can be obtained. Therefore, the type selection of the BESS and the difference of different physical performance evaluations can be fully analyzed, so that the BESS analysis is relatively comprehensive.
