Energy storage capacity planning method for urban integrated energy system considering uncertainty

Abstract

Abstract The conventional energy storage capacity planning method of urban integrated energy system has the problem of fuzzy coupling characteristics, which leads to the small energy storage capacity. A planning method of energy storage capacity of urban integrated energy system considering uncertainty is designed. Calculate the expected output value, to determine the optimal control targets, considering the uncertainty of power load forecasting, load combination forecast load density and space distribution, identification of urban comprehensive energy system coupling characteristics, optimize the distribution ratio of different energies, capture of power and steam energy, energy storage capacity planning design method. Experimental results: The average energy storage capacity planning method of the urban integrated energy system in this paper is 103.844MWh, 91.657MWh and 91.152MWh compared with the other two methods, indicating that the designed urban integrated energy system energy storage capacity planning method is more perfect after fully considering the uncertainty factors.
