Real time electricity price information interaction method of intelligent power distribution network and based on load sensitivity

Abstract

The invention provides a real time electricity price information interaction method of an intelligent power distribution network and based on the load sensitivity, and relates to a real time electricity price pricing method allowing for load geography distribution and user electricity consumption characters. The real time electricity price information interaction method comprises a first step of acquiring network parameter information of a distribution system from a distribution automation system; a second step of acquiring load predicted data on the second day from a load prediction system; a third step of calculating electric power demand elasticity values of various loads at each time in dependence on data read by the second step; a forth step of calculating the flow distribution of the power distribution network in 24 hours by utilizing a power distribution network forward-backward sweep calculation method; a fifth step of calculating a sensitivity value of each node of the power distribution network in 24 hours; a sixth step of calculating a real time electricity price of each node; and a seventh step of outputting and publishing real time electricity price information comprising electricity price information of each type of load in 24 hours to a marketing system. The real time electricity price information interaction method can be adjusted in dependence on different regions and different user types, and is strong in adaptability.

Description

technical field [0001] The present invention is used in the field of smart distribution network marketing, which utilizes the response of existing distribution network users to the price of electricity, the distribution of users in the distribution network, and the characteristics of users' electricity consumption to realize real-time monitoring of the distribution network. The electricity price interaction scheme belongs to the application field of intelligent power distribution and utilization technology. Background technique [0002] The smart distribution network is an important part of the smart grid, and its main features are self-healing, optimization, coordination, interaction, distribution and integration. Among them, interaction is the key technology of smart grid. As the end of the power system, the distribution network is directly connected to users, and its interactive ability directly affects users' participation in power grid operation. The electricity price...

Problems solved by technology

[0003] In my country, the real-time electricity price has not been fully implemented, and the real-time electricity price has only been implemented on the power generation side. The real-time electricity price on the user side that participates in demand response has not yet been implemented. However, with the construction of the smart distribution network, users participate in grid interaction. The information interaction method of real-time electricity price on the power distribution side needs to be solved urgently
