Description
Technical Field
The present invention relates to an incentive response mechanism, and more particularly, to a demand response incentive method and system considering user response characteristics.
Background
With the rapid development and the technological progress of social economy, controllable resources of a demand side distributed power supply, an electric automobile, distributed energy storage, an air conditioner, an electric boiler and the like on a user side are rapidly increased, and the types and the capacities of demand response resources of the user side are greatly enriched. In addition, with the new energy grid connection with a large amount of output uncertainty and the further expansion of peak-to-valley difference, the power demand response, especially the incentive type demand response, has become an important means for solving the supply and demand balance, and the existing research on the incentive type demand response does not take the response characteristics of different users into consideration. Therefore, a demand response incentive strategy considering user response characteristics is a difficult problem to be solved urgently at present, and it is particularly important to coordinate supply and demand balance of energy and guarantee satisfaction of users based on incentive strategies at different time periods.
The prior art electric power demand response methods mainly include a price-based demand response method and an incentive-based demand response method. Wherein the price-based demand-side response strategy is divided into time-of-use electricity prices, peak electricity prices, and real-time electricity prices. The time-of-use electricity price is a common electricity price strategy in China, can effectively reflect an electricity price mechanism of power supply cost difference of a power grid in different periods, and mainly takes measures of properly increasing the electricity price in a peak period, properly reducing the electricity price in a valley period, reducing load peak-valley difference, improving electricity consumption of users and achieving the effects of peak clipping and valley filling. However, the time division of the time-of-use electricity price is fixed, and the electricity price ratio of each time period is also fixed, so that the time-of-use electricity price can only reflect the statistical rule of daily load and power supply cost in a period of time, and the change of the daily time-of-use load and the power supply cost cannot be accurately reflected. The incentive type demand response is that a market participant releases a subsidy signal to a user to guide the user to increase or decrease electricity for a certain period of time to achieve balance of supply and demand. However, in the existing incentive subsidy research, the differentiated response characteristics of different users are not considered, so that the incentive strategy cannot achieve global optimization.
