Embodiment Construction

[0029] The definition of real-time electricity price is the marginal cost of electricity production. When the market is perfectly competitive, the total social benefit can be maximized. In a perfectly competitive market, commodity prices are equal to their marginal production costs, which is also the economic theoretical basis for using real-time electricity prices. assuming p i is the real-time electricity price charged to the i-th user at a certain moment, d i is the electricity demand of the user at that moment, and C is the total cost of electricity production to meet the electricity demand at this moment, then

[0030]

[0031] The concept of active real-time electricity price can be easily extended to reactive real-time electricity price, that is, the reactive real-time electricity price is equal to the change rate of the total system operating cost caused by the change of user's reactive power demand. The reactive power real-time price is derived by using the OPF ...

Abstract

The invention discloses a reactive power price pricing method based on AC power flow, which is characterized in that the real-time reactive power price is derived by using an OPF model that minimizes cost. The loads are all constant, then the OPF objective function can be expressed as: min i mi z e C = C q ( Q i ) = Σ i = 1 N g C g i ( Q g i ) + Σ i = 1 N d g C r g i ( Q r g i ) + Σ i = 1 N c C c i ( Q c i ) .

Description

technical field [0001] The invention relates to the technical field of reactive power auxiliary service pricing, in particular to a reactive power price pricing method based on AC power flow. Background technique [0002] With the gradual deepening of the power marketization process, the pricing of reactive power auxiliary services has attracted the attention of many researchers. At present, no country has established a real-time reactive power market in the true sense. In most of the literature, the reactive power production cost of the generator is not considered in the OPF model, which is not conducive to the construction of the reactive power service market. Contents of the invention [0003] The purpose of the present invention is to provide a reactive power price pricing method based on AC power flow, which will analyze the real-time reactive power price of the OPF model with the goal of minimizing the reactive cost after taking into account the reactive power produ...
