[Abstract]:In the 21st century, the progress of society, the development of economy and the upgrading of technology have put forward higher requirements for the quality of power supply service and the development of electric power network. With the deterioration of environment and the emergence of energy crisis, the concept of smart grid has emerged as the times require, and has become a hot topic in the global power industry in recent years. "Smart interaction" is the goal and main feature of smart grid construction, including the interaction of information and energy, to encourage users to change the traditional methods of using electricity, to participate actively in the operation of power grid, and to adjust the power mode according to the real time electricity price. Can realize the distributed power "plug and play" power network connection operation mode. With the development of smart grid, demand-side management has been given some new connotations. Demand-side management is an indispensable part of smart grid. It is the key factor that decides whether the smart grid can be successfully implemented. As an important technical means of demand-side management and an important support means of demand response, the power load management system can effectively realize the real-time monitoring of power load and improve the characteristic curve of electric load. It is of great significance to reduce the valley difference between peak and low peak power consumption, to realize the optimal distribution of power load, to reduce the loss, and to improve the utilization ratio of power generation, power supply and electrical equipment, which is of great significance to the improvement of economic efficiency and the implementation of energy-saving countries. In this paper, based on the background of smart grid construction, the necessity of power load management system construction is obtained by analyzing the current research situation of power load management system at home and abroad, and the relevant theoretical knowledge of power load management system and smart grid is expounded. System analysis of power load management system is carried out from three aspects: feasibility analysis, frame contrast analysis and benefit analysis. The system evaluation index system is constructed by using the analytic hierarchy process (AHP), and the power load management system and the electric load control system are evaluated. It is concluded that the power load management system is superior to the load control system in smart grid orientation. Combined with the practical application of the load management system in Tangshan area, based on the evaluation criteria obtained from the analytic hierarchy process, the improvement analysis of the power load management system is carried out from the two aspects of the system economic benefit and the management strategy. The power load management system conforms to the basic requirements of intelligent power consumption in the environment of smart grid, is the necessary measure to implement the planned electricity consumption, and is also the technical means to save electricity and to use electricity safely. It is also an important part of electric power marketing and customer service, which has remarkable economic and social benefits. With the deepening of China's reform and opening up and the development of power industry, it will play an increasingly important role in the process of smart grid.
