Research On Electric Power Pricing System Based On Power Quality

With the development of science and technology,industrial development is more and more mature,the total demand of electricity is increasing year by year,and with the energy production and consumption,the development of electric power market is more mature too,in the power market,the power quality in the evaluation and testing has become essential the factors and the power quality can be regarded as the power service important content,must be solved in the power market environment,this has gone beyond the technical problem in the production operation of the power system,related to social justice and the allocation of resources and economic problems,must increase the power quality management investment,and make investment through the price return.Therefore,the need for research through the existing theory,put forward a kind of power quality classification method based on effective pricing,which can not only guarantee the power user's economic interests,has also become a power supply company of power quality dynamic optimization and improvement,and to provide more high-quality electricity,we need investment and the management of the larger,so it should be a greater return,due to the realization of power market,electricity as a commodity into the market to achieve this property."The quality of electric energy supply" and "pricing".This paper mainly presents a new kind of power quality grading pricing model for both demanding side and supplying side.The main work of this paper is shown as follows:(1)Firstly,this paper introduces the statistics for power quality problems caused by the economic losses abroad,show that the current power quality in the power service now is an important indicator of the power supply company in the future in addition to considering the settlement price in addition to power generation,transmission and ancillary service cost,should be fully consider the quality of service cost.Then introduction of the domestic and foreign existing considering power quality pricing methods at home and abroad power quality management program is presented,based on this basis leads to analysis of electric power market environment to implement the market environment and technical conditions of pricing.(2)Secondly,this paper puts forward the definition and problem of power quality,and introduces the measures and methods to improve the quality of point energy,and then puts forward the division of power quality.For the quality of division of power,the power quality evaluation model is established,considering the power quality index,after using AHP to comprehensive power quality evaluation,and the power quality is comprehensively evaluated after obtaining the weight of each index of the power quality.And the evaluation methods used for example analysis.(3)Finally the power quality grading pricing model is established,power quality grading pricing process is studied,then the high quality power supply cost is calculated,based on the established classification pricing model,and taking a county power supply company electricity calculation of boundary conditions and the power quality cost basis.Before the application described the power quality of the economic cost structure of power quality evaluation,developed a high quality power supply scheme,the original price calculation,the power quality of additional price is calculated,and an example for the analysis and verification.Finally,a supply-side cost optimization design model is established,which is optimized by the particle swarm optimization algorithm.The feasibility of the optimization is verified through simulation.
