Embodiment

[0021] Example: such as figure 1 As shown, a smart grid-based power generation dispatching method considering user-side interaction includes the following steps:

[0022] (1) The dispatch center predicts the user load curve based on the user response principle of time-of-use electricity price based on consumer psychology, and publishes basic electricity price information;

[0023] According to the user load curve, users have different responses to different prices; the load transfer rate is the ratio of the amount of load transferred from the high electricity price period to the low electricity price period after the time-of-use electricity price is implemented, and the high electricity price load. The load transfer rate is proportional to the electricity price difference between peak-level, peak-valley, and flat-valley. A user response model based on load transfer rates can be approximately fitted to a piecewise linear function as shown below:

Abstract

The invention relates to a meter and user side interactive power generation dispatching method based on an intelligent power grid. The method comprises the following steps: firstly providing a user load curve, which is obtained by predicting based on a time-of-use electricity price user response principle of consumer psychology; then considering coordinated optimization of interruptible standby and generation side standby; and finally comprehensively measuring various interests, selecting an optimal time-of-use electricity price and optimal interruptible standby capacity in lowest power generation cost, and making a plan of power generation dispatching. Beneficial effects are that the method selects the optimal time-of-use electricity price and the optimal interruptible standby capacity on the basis of comprehensively measuring various interests, and makes the plan of power generation dispatching whose power generation cost is lowest, so as to bring material benefits for users, and power generation cost is optimized.

Description

technical field [0001] The invention relates to the technical field of smart grid power generation scheduling, in particular to a smart grid-based power generation scheduling method that takes into account user-side interaction. Background technique [0002] Smart grid is a major scientific and technological innovation and change trend of the power system in the 21st century, and it is a research hotspot in the power industry today. As a new type of intelligent service network, the smart grid is characterized by flexible integration and scheduling of demand-side resources through the creation of open information systems and shared information models, especially emphasizing the two-way interaction with user information and electric energy; encouraging users to change traditional Actively participate in the operation of the power grid, adjust the power consumption mode according to the real-time electricity price; further optimize the operation and management of power infrastr...
