Household energy management optimization scheduling method and system

Abstract

The invention relates to a household energy management optimization scheduling method and system. The method comprises the following steps: obtaining the time-of-use electricity price information of a scheduling system in each optimization time period and the demand response information of household equipment, and substituting the time-of-use electricity price information of the scheduling system in each optimization time period and the demand response information of the household equipment into a pre-established household energy management system optimization scheduling model to obtain a household equipment scheduling strategy corresponding to each optimization time period. According to the technical scheme provided by the invention, the power utilization comfort of the user is considered while the user cost is considered, the load response potential of the household appliances and the charging and discharging capacity of the energy storage battery are fully utilized on the premise of ensuring the user satisfaction and the user power utilization cost, local consumption of distributed roof photovoltaic is promoted, meanwhile, the energy storage battery stores the photovoltaic surplus electric quantity and discharges electric energy at the peak electricity price, and the load is transferred from the peak electricity price to the valley electricity price, so that the electricity consumption expenditure of the household user is saved, the household energy income is improved, and the electricity consumption comfort of the user is considered at the same time.

Description

technical field [0001] The invention relates to the field of energy Internet, in particular to a family energy management optimization scheduling method and system. Background technique [0002] With the rapid development of the global economy, the demand for electricity continues to increase, and the world's energy crisis and global warming are becoming more and more serious. At the same time, smart grids have appeared in people's vision, providing new development space for the power industry. As an important part of the smart grid, users play an important role in improving the operating efficiency of the grid, and are gradually changing their roles into active participants. The home energy management system (HEMS) has developed rapidly because of its good economy and reliability in terms of user needs. Residents can use various information in HEMS to reasonably arrange electricity consumption. Therefore, the home energy management system undertakes It is an important task...

AI Technical Summary

Problems solved by technology

[0003] At present, a new home energy management system has been introduced in the research on home energy management system (HEMS) to reduce daily home energy costs and maximize user benefits through self-consumption of photovoltaic energy. The results show that although the model can largely Increase the user's income, but the utilization rate of new energy is not high, and the peak shaving effect is not obvious; on the other hand, combined with distributed energy resources and energy storage systems, a simple and efficient real-time smart home energy system is proposed, which reduces The energy cost of household appliances, but this model only considers the reduction of electricity bills, which requires a higher degree of home intelligence and more stringent technical requirements
