【Abstract】 In order to solve the problem of energy waste caused by the increasing demand for household electricity and the unreasonable mode of household electricity consumption, the typical controllable energy efficiency load of air conditioning, water heater and lighting is analyzed, and the mathematical model of load energy consumption is established. According to its operation characteristics, combined with the electricity consumption habits and time-of-use prices of household users, the optimization strategy of the controllable energy efficiency load of household users is made for, and with the electricity cost and the satisfaction degree of household users as the object, the optimization model is set up. To improve the speed and accuracy of harmonic search algorithm, parameters are dynamically adjusted and integrated with differential evolution algorithm to optimize the solution of controllable energy efficiency load.. The example results show that the improved algorithm has better convergence and higher accuracy, verifies the feasibility of the optimization strategy, and achieves the idea of optimal management of controllable energy efficiency load from the perspective of demand response.更多还原
