Research on Optimal Configuration of Energy Storage for High-Power Pulse Power Supply System

In this paper, the performance of the energy storage device of a high-power pulse power system is evaluated and optimized based on the minimum mode ideal point method with weight and analytic hierarchy process. The evaluation process fully considers the system requirements and load characteristics, takes volume, weight, economy and reliability as the main components of the evaluation function, and takes power, energy, response speed, voltage, state of charge and other parameters as the system constraints. Based on flywheels, metalized film capacitors and supercapacitors commonly used in pulse power energy storage systems, the optimal configuration model of energy storage devices is established, and the differential evolution algorithm is used to solve the optimal configuration scheme. Taking the magnetic confinement fusion pulse power supply as an example, the evaluation results show that the performance of the supercapacitor is the best under the steady-state long pulse superimposed high power short pulse working system.
