Development Of Power Demand Side Management In The Smart Grid Based On The Analysis Of Power Load

Power demand side management (DSM), a crucial part in the smart grid construction, is an important means to achieve reasonable social energy saving and the necessary choice to support national economy and sustainable development of power industry. It also promotes the energy-saving and emission-reduction of the whole society.With the deeper construction of smart grid, the study of DSM in content system and management methods has been greatly expanded and improved. The continuous development and innovation of DSM is facing a higher demand for development. Focused on the development of the DSM system and relevant theories based on load analysis in smart grid, the following contents are explored in this study:(1) The development process of smart grid and the content system of DSM are explained, and the system of DSM and relevant management means in smart grid are expanded.(2) Methods of Power load demand forecasting in smart grid and the optimization of system management are deeply studied. A load forecasting idea based on model base optimum selection theory is proposed, and a mid-long term load demand forecasting method based on combined forecasting theory is built, and comparison of the models of short-term daily maximum load demand forecasting method based on model optimum selection theory. Empirical study are given to put forward advisable plans for optimizing load adjusting.(3) The development of virtual power plant and its optimization management based on load demand analysis in smart grid is studied. The value of virtual power plant is analyzed, the evaluation index system of virtual power plant is established, and the evaluation model based on network AHP is proposed. Empirical study is also implemented.(4) The issue of the connection of distributed energy based on load demand analysis in smart grid is deeply analyzed, and an optimized management system based on the integration of Location-Pattern-Path.(5) The issue of energy-saving reform of electric equipment based on load demand analysis in smart grid is studied. The importance of energy-saving reform of electric equipment is analyzed, the evaluation index system of construction energy conservation is established, and the evaluation model based on matter element extension model combined with AHP is proposed. Empirical study is also implemented.(6) The development of DSM in smart grid is summarized and prospected in the area of extra-high voltage power grid construction and electric vehicle utilization.The research in this paper provides reference for expanding the DSM based on load analysis in smart grid, and sound theoretical support for improving DSM standard.
