Research On The Political Recommendations And Evaluation Mechanism Of Smart Grid's DSM

With the rapid development of Smart Grid technology, it is bound to bring about profound changes to the demand side of the grid. How to deal with these new technologies and new changes which are so different with the traditional grid, it poses a severe challenge to DSM of power system. Therefore, the traditional political system of DSM is no longer suitable. National power system researchers should be effective to propose the new political system of DSM in the era of smart grid for rapid development of grid with new theories and methods, to solve the variety of prominent structural contradictions in the new power system.The paper is based on the specific impact and changes in the grid by the development of Smart Grid. It points out that the problems of China's traditional political and mechanism system of DSM under these influences, and propose the more reasonable political recommendations with the issues above and the national research applicability status, then the political recommendations are evaluated and validated by theoretical analysis and modeling.Firstly, the development and changes of power systems around the world under Smart Grid are described, and three specific changes in demand-side—DG, PHEV and Energy Storage technology are Summarized. After that the specific impact to the power grid by the three demand-side changes is analyzed.Secondly, the specific political recommendations and mechanism are proposed related to DSM of three kinds of demand-side changes in China's power grid in this paper, which is based on the specific impact by DG, PHEV and Energy Storage technology, and the advanced experience and practice on Smart Grid's DSM from the other countries.Then, in order to properly assess the reasonableness of political recommendations of DSM proposed, the Evolutionary Game Theory is introduced, which is synthesized by the classic game theory and the theory of evolution, political recommendations of DG's DSM, one of three changes in the demand side, is modeled and evaluated by the application of Evolutionary Game theory, and the relevant specific evaluation index system is obtained.Finally, with specific numerical example, the evaluation index of political recommendations for DG's DSM is actually calculated, Numerical results has proved that, the corresponding effect of the specific political recommendations is achieved, and reasonable.The paper has made the overall research and analysis about the DSM mechanisms under Smart Grid, proposed the specific political recommendations, and Evolutionary Game Theory for policy evaluation, and the final research results is very beneficial to build content and long-term DSM mechanism of Smart Grid.
