Research On Demand Response Control Strategy For TCLs Of DEWH Type In Smart Community

The development of wind power and photovoltaics in China has been booming,but the capacity for new energy consumption is very low.There are serious problems of abandoned winds due to the anti-peaking characteristics of wind power and the intermittent nature of wind power photovoltaics.The paper uses a re-energized smart community and wind power to form a virtual power plant and conducts research on the control strategy of temperature control loads for electric water heaters.1)The so-called hierarchical energy management control structure for smart communities and users based on home energy management systems have been established.Grid interaction system;2)Evaluating the demand response potential of temperature control loads for electric water heaters based on load characteristics indicators,and presenting an improved model for electric water heaters;3)Establishing a load aggregation model based on Monte Carlo method,and considering the willingness of users to respond Household electric water heater load participates in the control strategy of demand response in real time;4)Simulation verification is performed.The strategy expects to improve the problem of wind erosion caused by wind power intermittentity and anti-peaking characteristics,and integrates the community residents' user load and the wind farms in and around the community into a virtual power plant.The user's right to participate in the demand response and the right to know Demand response intelligent control combines organically,fully considering the user's willingness to respond and water temperature acceptance and other comfort constraints,and comprehensively guaranteeing the user's comfort in the scheduling process through the integrated state priority queue algorithm.Simulations show that the rate of wind rejection has decreased from 49.2% to 25.5%,which verifies the effectiveness and economy of the strategy.
