Research On Power Marketing Strategy Based On Demand Response

With the development and progress of science and technology,the electric power industry is playing an increasingly important role in the social economy.Especially after the information technology revolution,electric power has played an indispensable part in people's daily life.Whether the electricity market can be healthy,stable and sustainable development,to protect people's work and life,has become a topic of concern.Since the 1970 s,in order to meet the growing demand of the electric power industry,all countries in the world have reformed the electric power market,changed the original monopoly mode of vertical integration of production,transmission and marketing,and introduced competition factors into the electric power market.At present,China is carrying out the reform of the electric power system.The policy of "grasping the intermediate links and opening the two ends" is to open the door of the electricity sales market,grasp the intermediate transmission module,introduce personal capital into the electricity market,and make the electricity market diversified.This paper mainly studies the real time electricity price in response to the demand of residential electricity.In this paper,the concept and classification of demand response are introduced,and the R&D process and development status of demand response in China,Europe and the United States are described in detail.Then,based on the interests of retailers and the interests of the demand side,the objective optimization model is established.The objective function is to maximize the sum of retailers' interests and user utility.Demand elasticity and user responsiveness are added to constraints rather than real-time.The real-time electricity consumption without subsidy mechanism is analyzed by numerical simulation of real-time data of a city.After simulation,users will change their electricity consumption mode according to the change of electricity price.On the other hand,the user's response to electricity price also has an impact on the interests of the power selling enterprises.Finally,the overall structure and content of the article made a comprehensive summary,and according to the results of the article,put forward some suggestions and opinions.
