Research On Demand Side Management

Electric power is the pillar of economy development and city function. In recent years,electric power shortage was very common in china,.It results in a series of problems such as high cost,low power supply reliability and power brownouts. Under such circumstances, in order to solve the contradiction between the supply and requirement of power resources, demand side management was born. As the measure of regulating economy working and e management technology of power demand,DSM has been paid great attention of the whole society. It has been playing an importment role in promating coordinated development of the electrical industry,environment, economy and societyDSM includes some kinds of management activities under the support of law and policy by the government. It takes effective motivate measures and suitable operation, through the joint power of power companies, service companies, intermediaries and the supplier and power users to improve the efficiency of electricity and the improvement of the electricity supply of electricity in the same way.The best result is to meet all the functions of electricity consumption and reducing demand for electricity, achieve the gole of saving resources and environment protection and realization of the best social benefits, the lowest cost of energy services.This paper mainly adopt the combination methods of standardized studies and empirical analyses, static analysis and dynamic analyses to study the DSM issues in china.The basic content as following:firstly, analysis the principle of supply and demand and DSM in classic economy as the theoretical foundation of DSM study. At the same time,analysis the background of electricity marke's development and it's propeties with power economic theory.The environment of electrical product and its characteristics determine that it is difficult to use complete manner of commercialization.To increase the elasticity of electricity demand, the government need to strengthen the demand side management and control,achieve coordination and sustainable development of society, economy,natural resources and environment.Secondly, design DSM learning from the ideas and operation mode of pollutant right discharging,trying to solve the externality of power saving.The article has designed main targets including volume control,the standard of consumption,transaction system and market supervision and management.Thirdly, study encouragement mechanism learning from principal-agent theory to solve the obstacles of DSM implementation, create favourable development environment,promote the depth and extent of DSM.Forthly,evaluate the effect of DSM from the following three aspects:economic benefits, environmental benefits and overall social development efficiency.And use uncertainty analysis methods to implement the market analysis, so provide the basis of policy-making for the government and electricity companies to take effective DSM means.At last, this paper also analysis the method of DSM operation with the example of interruptible load and time-of use.I think, to maintain the reliability of electrical power system and improve market operation efficiency,the government should give consumers the right of option in the service and price of electrical products, lead them to accept the price that most benefical to themselves.The innovation points are:an overall analysis of DSM's basic theories and efficiency evaluation methods; the first time to creat the concept of "power-saving deal",make it clear that pollutant right discharging and DSM can be combined greatly;study encouragement mechanism learning from principal-agent theory to solve the obstacles of DSM implementation;the systematic study of DSM.
