Embodiment Construction

[0053] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0054] In smart grid, demand side users usually refer to energy consumption users equipped with DG and / or DS equipment. Through the analysis of the cumulative expenditure of a single demand-side user in the smart grid, the pre-optimization process is used for renewable energy, and the non-cooperative game theory method and Nash equilibrium theory are used to solve the cumulative expenditure function f of the demand-side user n and the corresponding Nash equilibrium point.

[0055] (1) Based on the smart grid model proposed by the demand side user

[0056] In the smart grid, we divide demand-side users into two categories: active users and passive users. Usually, passive users refer to basic energy consuming users, just like traditional demand-side users. Active users refer to users who participate in the optimization ...

Abstract

The invention provides a management method of an intelligent power grid demand side. The method comprises the steps that (1) modeling is carried out based on a demand side user; (2) renewable energy sources are optimized in advance; and (3) the game theory is used for solving an accumulation expenditure function of the demand side and a corresponding Nash equilibrium point in an optimization mode. According to the method, renewable energy sources are used in distributed generation, the mode that the renewable energy sources and non-renewable energy resources are used for generating energy resources at the same time is used, energy source transmission cost and production cost are lowered, and the problems that in a traditional power grid, environmental pollution is severe, and demand side user expenditure is high are solved. In addition, from the point of sustainable development, using of the renewable energy sources is beneficial for sustainability of ecology, society, economy and science and technology, the using rate of natural resources is improved, and harmony between man and nature is promoted.

Description

technical field [0001] The invention relates to a smart grid management method, in particular to a smart grid demand side management method. Background technique [0002] The services provided by the smart grid to users have the advantages of high security, high quality and high economic efficiency. The development of the smart grid has also greatly promoted the development of the low-carbon energy industry, ensuring the sustainable use of renewable energy and adapting to the current low-carbon environmental protection requirements. The so-called smart grid demand side management refers to the process of improving the time pattern and demand range by encouraging demand side users to actively participate in the advanced mechanism of network optimization. [0003] The main parts involved in the development of smart grid include concepts such as demand-side management (DSM: Demand-Side Management), distributed energy generation (DG: Distributed energy Generation), and distribu...
