[Abstract]:In recent years, with the rapid development of smart grid technology and the deepening of demand response, the development space of electric energy efficiency and interaction service between power grid and users is increasing. Intelligent power use is the key to solve the related problems in these fields, and it is also an important part of the smart grid. At the same time, with the popularity of distributed energy on the residential side and the development of smart home appliance industry, the user side power consumption mode is more flexible, and it also opens up a new path for intelligent power consumption. From the present study, the research of electricity technology in intelligence, most are concentrated in the terminal equipment of the system development, network communication technology and other hardware features, while the appliance or storage devices such as how should the specific operation, or too much reliance on the user to decide, there is no real "smart". Therefore, how to apply the power demand response information, equipment parameters, user personality requirements and other related functional data, it is particularly necessary for users to adjust their energy structure more actively, and make more economical and rational planning of electricity consumption. The research object of this paper contains photovoltaic, energy storage and smart appliances user side micro grid, designed an optimal operation strategy of active load control based on the strategy according to the characteristics of all kinds of electrical equipment for its optimization, finally achieve the purpose of saving energy and economy. This paper firstly introduces the related theoretical basis, including the active load demand response technology, relevant content and user side energy management of micro grid, the active load technology is the starting point of the intelligent electrical, physical basis of the user side of micro grid energy management; demand response is intelligent power direction application part to the user side micro grid energy management; to the user side of micro grid energy management focuses on the functions and characteristics of each functional module in energy management system. Secondly, each part of this paper on the user side in the micro grid are modeled, including topology, distributed power optimization and participate in the operation of several active load model, combined with the user side model characteristics of each part in the micro grid is proposed for the step-by-step optimization strategy of different types of load, the load can be controlled with temperature control load characteristics, proposes an optimization strategy based on Nash bargaining theory, through the analysis of temperature load satisfaction and using the relationship between the economy to develop its operation plan; load transfer uses the optimization strategy of electricity cost minimization for electric vehicles. Finally, design examples to verify the validity of the proposed scheme, and in the MATLAB platform programming for optimal operation of adjustable load respectively using genetic algorithm and fmincon function method and the results were compared and analyzed, for optimal operation of the load transfer using a mixed integer linear programming method, at the same time this paper highlights the superiority of the proposed scheme, also made the corresponding comparison. The results show that the designed scheme can quantitatively and dynamically analyze the economy and satisfaction of the temperature control load, and adjust it based on it. At the same time, for the whole user side microgrid system, it can effectively adjust the load peak and valley relationship and improve the operation benefit of the system.
