Demand response complementary electricity price system and method for high-component flexible load

Abstract

The invention provides a demand response complementary electricity price system for a high-component flexible load. The demand response complementary electricity price system comprises an optimal demand side response complementary new electricity price making system, an identification judgment module, a power grid dispatching module, a high-component flexible load user group and other user groups,the optimal demander response complementary type new electricity price making system comprises a target function module, an index constraint module and an optimization algorithm module. And the target function module comprises an optimal user load calculation module and a power grid dispatching simplification optimization module. A demand response complementary electricity price method for the high-component flexible load is provided, and the mathematical model established by the optimal user load calculation module is solved; a mathematical model established by the power grid dispatching simplification optimization module is solved; optimization calculation of an optimization algorithm module is carried out; an the mathematical model established by the power grid dispatching module is solved. The power grid cost responded by the optimal demander is obtained and serves as a new electricity price framework core, the high-component flexible load group is promoted to change the electricity consumption behavior, and off-peak electricity consumption is achieved.

Description

technical field [0001] The present invention relates to the technical field of power systems, and more specifically, to a demand response complementary electricity price system and method for high-composition flexible loads. Background technique [0002] The future development trend of the global power system is smart grid. Demand response, as one of the protagonists, promotes users to use electricity more efficiently with the help of interoperability between power companies and users. Through demand response, utilities gain a mode of operation in demand-side management that affects the characteristics of electrical loads. In network operations, demand response helps to reduce peak electricity demand, thereby alleviating expensive or urgently generated electricity demand, such as the need for spinning reserve. [0003] Demand response can be divided into two categories: the first category is time-based demand response; the second category is incentive-based demand response...

Problems solved by technology

[0007] In order to solve the problem that the time-of-use electricity prices of all users in the area are the same under the traditional time-of-use electricity price mode, which weakens the effect of "shaving peaks and filling valleys", and makes up for the lack of a complementary electricity price mechanism based on demand response, it provides a oriented Demand-response complementary electricity pricing system and method for high-composition flexible loads
