The Research Of Electric Tariff Strategy Of Dalian Based On Demand-side Management

With the challenges of global energy crisis and the deteriorating global environment, energy-saving and emission-reduction has become important issues for electric power industry which is the support for social development and economic development. Generation side and customer side are important links to realize energy-saving and emission-reduction of the electric power industry. And the realization of energy-saving and emission-reduction in the customer side will be depended on the demand side management. Substantial researches and practice applications prove that the demand side management is a widely used and effective power saving mode.The electricity price is the main tool of demand side management to regulate the electricity market. The main content of demand side management is that the power users adjust their consumption habits and demands according to the changes of electricity price. And it can encourage the rational use and conservation of electricity. Many price strategies based on demand side management, such as step tariff, time-of-use tariff and real-time pricing, have been studied and implemented at home and abroad and a lot of valuable experiences have been obtained.The electricity price and demand side management of China are studied in this paper. The relationship of demand side management, electricity price and electricity reform is analyzed and the influence of the factors of demand side to the electricity price is studied.Some electricity price strategies based on demand side management which have been implemented in our country are analyzed and compared in this paper. The step tariff is very suitable for the present demand of the electric power market in China. The step tariff can protect low-income energy supply and encourage the energy saving. It is of great significance for regulating the contradiction between supply and demand, promoting energy-saving and emission-reduction and reforming the future electricity price. And it has positive significance for training the reasonable power consumption of electricity users.With the economic development in Dalian, the demand for electricity is growing. And the high energy prices must make the situation of power supply and demand tends to be serious in Dalian. According to the analysis of the power market of Dalian, the step tariff is presented and the price strategy is studied. The direct and indirect benefits after implementing the step tariff are analyzed and some suggestions are proposed to overcome the current problems. This paper can be provide a reference for the reform of electric power market in Dalian in the future.
