Research On Household Electricity Load Control Strategy Based On Demand Response

With the gradual deepening of the electricity reform, breaking monopoly,introducing competition mechanism good, optimizing resource allocation gridand improving the operating efficiency of the electricity market become thedirection of electricity reform in China. The price feedback of electricitydemand-side is essential for a good market. Microeconomics theory pointed thatthe biggest be gained in market when the energy price on a common decision ofthe supply and demand sides. Therefore, the introduction of grid demandresponse(DR) mechanisms is inevitable in future. In order to maintain stableoperation of the power system, solve the peak power shortage and low powerconsumption low resource utilization problems, demand response programsencourage users to actively participate in the management grid and make apositive response to demand response program. How ordinary home usersrespond to demand the implementation of the project could be better to controlhousehold load and manage home energy based on price signals. so that reducingenergy consumption and electricity cost while further achieving load shifting andoptimizing the allocation of resources. This problem is one of the key issueswhich will determine the electricity market success or not in the future.First, this paper introduces the concept of demand response, the DRimplement required to technical conditions and country’s existing policies aboutDR. Detailed analysis be made about DR which ones have been implemented inlarge industrial users in some provinces of China’s and foreign country.Second, According to the habits of residents of China use home appliances,TOU DR project was proposed combined with the existing technical conditionsand demand response project implementation. Classification analysis was madein home loads which involved in the TOU project. Different control objectivefunctions were proposed for the different characteristics of different loads.According to the objective function this paper designs a home energymanagement optimization algorithm，and calculate feasibility analysis of the algorithm.Finally, According to load control objective function，this paper programand simulate home energy control optimization algorithm in MATLAB platform.Including single-user, multi-user, constraints of optimization algorithm and theprice level of demand response programs et al, various factors which ones couldaffect the simulation results of home energy control the will be analyzed. Theresults show household electricity load control, optimize resource allocation,load shifting and electricity savings can be achieved through the control strategythis paper proposed based on demand response.
