Building comprehensive energy system scheduling method based on building characteristic and virtual power plant

Abstract

The invention relates to a building comprehensive energy system scheduling method based on building characteristics and a virtual power plant, and the method comprises the steps: building a building virtual energy storage model system and an electric vehicle virtual power plant charging and discharging model, combining day-ahead scheduling with intra-day scheduling, setting the building virtual energy storage system as a long-time-scale scheduling device, setting an electric vehicle virtual power plant as a short-time-scale scheduling device, and stabilizing the power deviation of a tie line in a mode of combining long-time-scale scheduling of the building virtual energy storage system and short-time-scale scheduling of the electric vehicle virtual power plant so as to realize an intra-day scheduling strategy. The method has the beneficial effects that technical support can be provided for formulating a scheduling plan of a building integrated energy system, the energy management and comprehensive utilization level can be improved, the method can better adapt to the operation characteristics of the current building integrated energy system, the power deviation of a tie line is stabilized, and the resource utilization efficiency of the building integrated energy system is better played.

Description

technical field [0001] The invention belongs to the technical field of building energy, and in particular relates to a building comprehensive energy system scheduling method based on building characteristics and a virtual power plant, which is suitable for the two-stage coordination and optimization scheduling work of the building-level comprehensive energy system in the day ahead and within the day. Background technique [0002] The "China Building Energy Conservation Annual Development Research Report 2020" data shows that my country's total building energy consumption accounts for more than 22% of my country's total energy consumption. With the continuous improvement of my country's urbanization rate and the adjustment of industrial structure, this ratio will continue to increase. Therefore, energy consumption terminals represented by buildings have huge potential for energy conservation and emission reduction. Therefore, the development of the energy-saving and emission...

Problems solved by technology

This scheduling method issues all scheduling commands uniformly, and it is difficult to pre-perceive the state changes of the building system in the future period, and it is easy to deviate from the actual energy demand of the building, resulting in poor robustness of the scheduling scheme.
