New energy consumption-oriented user load directrix demand response method and device

Abstract

The invention discloses a new energy consumption-oriented user load directrix demand response method and device, and the method comprises the steps: 1, taking the minimum operation cost of a system as a target, considering the contribution proportions of traditional power generation and new energy power generation to different load nodes, and a line power flow constraint condition, calculating a most friendly CDL curve of each load node for new energy consumption; 2, a common domain is divided, and the contribution proportion of each generator to each load node is obtained; step 3, quantizing the actual effect of the user at the corresponding load directrix based on the calculated CDL curve, and taking the quantized actual effect as the basis for making the user to obtain the incentive subsidy; and step 4, establishing a user incentive subsidy quantitative model. According to the invention, the overhigh communication and control cost during large-scale user demand response can be effectively reduced, the system operation cost is greatly reduced, and the consumption of new energy grid connection is promoted.

Description

technical field [0001] The invention relates to the technical field of demand response, in particular to a large-scale user load alignment demand response method and device for new energy consumption. Background technique [0002] Due to the exploitation and use of a large amount of fossil energy, problems such as global warming and shortage of resources are becoming more and more serious. The new clean and renewable energy represented by solar energy and wind energy is developing rapidly and will gradually replace non-renewable resources as the main power generation method. However, the output of new energy is easily affected by unstable factors such as seasons and climate, and has obvious fluctuations and randomness, and its controllability is poor. The traditional method of supply-demand balance adjustment mainly relies on controllable units or a large number of curtailed wind and solar power, which is costly and inefficient, and cannot adapt to the current power grid wi...

AI Technical Summary

Problems solved by technology

The dispatch center needs to calculate the respective load baselines for each user participating in demand response, facing huge communication and calculation pressures

At the same time, when demand response is promoted on a large scale, events that require users to respond will occur frequently, resulting in insufficient load data for users' normal power consumption required by the dispatch center, making the calculation results inaccurate
