Optimal Dispatch of Integrated Energy System Including Electric Vehicles and Electric and Heat Demand side Respons

In order to improve the operating economy of the integrated energy system and the ability to absorb renewable energy, establish a price-based electric load demand-side response based on time-of-use electricity prices, and establish a thermal flexible load model based on the ambiguity of users" perception of temperature, and take electric vehicles into account An orderly charging and discharging model of electric vehicles with regular travel patterns. At the same time, the scenario analysis method is used to consider the uncertainty of new energy output. Construct a two-tier stochastic optimal scheduling model with the introduction of multiple demand-side responses. The upper-level model uses the price-based demand-side response inspired by the time-of-use electricity price, and takes the minimum net load volatility as the objective function to obtain the optimized electric load curve. The lower layer takes into account the flexible thermal load and the role of electric vehicles, and decides the output of each unit based on the total system cost in the dispatch period. The simulation example shows that the established integrated energy system dispatch model can effectively improve the system"s wind power and photovoltaic power consumption. Ability to reduce the operating cost of the system.
