Research On Trading Strategies Of Electromagnetic Pollution Emission Rights Of Disturbing Load

Power quality is significant to the safety and stability of power system operation, and it is meaningful to the eligible and credible power supply for users too. As the scale-up of grid and development of social economy and technology, there are increasing number of disturbing load be connected to grid, the effect on power quality of network brought by the emissions of polluting current become increasingly serious. So, the establishment of the theoretics system of electromagnetic pollution emission right, and bring the evaluation and management of disturbing load into market and competition is imperative.First of all, the economic property of some key factors in electromagnetic pollution emission right management system is demonstrated in this paper, and it also analyzed the social and economic profit of electromagnetic pollution emission right trading. Now, the study of electromagnetic pollution emission right theoretics system is just at the beginning, to clarify its economic property and signification can provide economic basis for the employment of economy and market measure to manage electromagnetic pollution emission right trading.Secondly, a simulation model of disturbing load under three voltage levels is established by PSCAD/EMTDC, and the grade limit of load disturbing property evaluation indexes is brought. AHP is used to calculate the weights of evaluation indexes, and the PSO-IIM is used to load disturbing property synthetically evaluate. It realized the qualitative analysis of load disturbing property, and the usage of example illustrated the feasibility of the method. Also, it proposed the measure of confirm users'electromagnetic pollution quantity according to their load disturbing to PCC in this paper.Lastly, on the base of clarified the economic property of electromagnetic pollution emission right trading, this paper elaborated the ways of emission right initial allocation, and discussed the advantages and disadvantages of them, and proposed a method for calculating the proportion of free allocation under free and paid-mixed way of initial allocation, and offered the reference to confirm users'initial electromagnetic pollution emission in practice.
