Emergency load shedding method of power grid considering user time fairness

Abstract

The invention discloses an emergent load switching method for a grid with the consideration to time fairness of users. The method comprises the steps: performing the statistical operation of the historical load switching data information of a grid load switching user; calculating the time fairness factor of the load switching unit; calculating the user group information of a to-be-switched load user; performing the load switching operation according to the user group information of the to-be-switched load user to complete the emergent load switching of the grid. The historical load switching data information of the grid load switching user is collected, a fairness factor of the load switching unit is calculated under the condition of consideration to the number of load switching times, time period and load switching duration, and the to-be-switched user group information is obtained according to an average user fairness difference minimum optimization model, thereby achieving the emergent load switching for the grid, and effectively improving the fairness of the load switching user for the emergent load switching operation of the grid. Moreover, the method gives consideration to the user data information of a user side, and gives consideration to the fairness, the stability and fairness, and is relatively simple and easy.

Description

Technical field [0001] The invention specifically relates to an emergency load shedding method of the power grid considering the fairness of user time. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an essential secondary energy source in people's production and life, bringing endless convenience to people's production and life. Therefore, ensuring the supply of electrical energy has become one of the primary tasks of the power system. [0003] Emergency load shedding is an important measure in the security and defense technology system of the power grid system. The purpose of emergency load shedding is to prevent the technical parameters of the power grid system (such as frequency, voltage, power angle stability, etc.) from exceeding the upper limit of the technical indicators, and to ensure the safe and stable operation of the power system. In some sudden situations, the p...

Problems solved by technology

However, since the existing load shedding operation only performs calculations and actions from the perspective of the power grid, the user side is only notified, or the load shedding operation is directly performed without any notification, which seriously affects the interests of users on the user side, and also caused a certain loss to the user
