Power demand side optimization method combining market demand response with physical demand response

Abstract

The invention relates to an analyzing and processing method for power user demand side, in particular to a power demand side optimization method combining market demand response with physical demand response. The power demand side optimization method combining market demand response with physical demand response comprises the following steps of constructing an optimization model for an interruptible load, then constructing an optimization model for a real-time electricity price, and finally obtaining a combined optimization model; and setting an optimal price at 24-t by only considering the real-time electricity price according to the combined optimization model, changing the electricity price at t+1, substituting the two prices into the combined optimization model under the condition of considering an interruptible electricity price, calculating whether a restraint is met, and finally calculating the benefit of a power supply company according to the optimal electricity price under the current interruptible load and real-time electricity price combined demand side management. The method has the effects that the market demand response and physical demand response common measure real-time electricity price and the interruptible load are combined, and the optimal combination acts on the power grid demand side, so that an obvious effect on management of the demand side is achieved; peak clipping and valley filling can be realized; the energy efficiency can be improved; and the power utilization mode can be optimized.

Description

technical field [0001] The invention relates to an analysis and processing method of the power user demand side, in particular to a power demand side optimization method combining market demand response and physical demand response. Background technique [0002] Smart grid is to centralize the behavior of all users, use advanced information technology, control technology and communication technology to save energy, reduce costs and increase the stability and transparency of the power system. It has reliability, high quality, high efficiency, compatibility, interaction, etc. It is the development direction of modern power grid. [0003] The power demand side management in the smart grid refers to the management of power consumption by taking effective measures to guide power users to optimize power consumption, improve terminal power consumption efficiency, optimize resource allocation, improve and protect the environment, and achieve minimum cost power services. the general...

Problems solved by technology

[0006] However, at present, demand-side management or a single focus on electricity price measures, a single electricity price measure cannot solve the problems of the power grid well, there is a certain lag, and the demand-side management cannot be carried out well; or a single Use of policy management - the initiative of peak shaving of interruptible load management is in the hands of the power supply company. Only in emergency situations of the power grid, the power supply company responds through interruptible load management to facilitate reliable and safe power supply
