Household Demand Analysis of New Energy Battery in Household Solar Power Generation System

Solar energy refers to the conversion of the energy of sunlight into electrical energy, which can provide electricity for household appliances. However, solar energy cannot be used directly on cloudy days or at night. The purpose of this paper is to design a new energy battery pack purchase plan for the household solar power generation system for a family to save solar energy for use at night and on a cloudy day. We first estimate the electricity consumed by this house in one night and on a cloudy day based on indicators such as the power rating and working hours. Then the price of the energy storage system is taken as the main consideration to establish an integer linear programming model. Based on the results of this model, we give the best selections for different types of batteries. In addition, we adjust and generalize the established integer linear programming model so that it is adaptable to different needs and preferences to choose the best battery storage. The battery capacity preference, the continuous power supply preference, and the instantaneous power preference are studied, respectively.
