Embodiment 1

[0068] In this embodiment, when the present invention is applied, the specific steps are as follows:

[0069] Step 1, the power dispatcher predicts the power situation of the system based on the load and power plant data in the real-time market, and obtains the power shortage;

[0070] In the real-time electricity market, when the power dispatcher predicts that the demand for electricity will change greatly at a certain moment, and the supply and demand of electricity will be unbalanced, the dispatcher of the power system will issue a demand response signal to the user in advance, and encourage the user to increase or decrease the load power through the price to meet the demand. real-time balance;

[0071] Step 2, in response to the power shortage situation, the power dispatcher issues a demand response signal to the society;

[0072] As electricity is a commodity, users will decide whether to participate in grid dispatching within a limited time according to their own risk t...

Embodiment 2

[0119] The power system single-line diagram of the IEEE-30 node used for simulation calculation in this embodiment is as follows Figure 5 As shown, it is assumed that conventional thermal power units are connected to nodes 1, 2, 5, 8, and 11, and controllable load users are connected to node 3, and the total power of controllable loads is 500MW. The coefficients of generator power generation cost function are shown in Table 3, and the coefficients of generator emission function are shown in Table 4.

Abstract

The invention discloses a controllable load demand response menu pricing method considering user risk preferences. By mining different risk preference characteristics of electric power users to a controllable load demand response, and taking demands of controllable load users as a guide, demand risk preference characteristics of different users are considered and user types are divided; and by taking a demand response electricity price and a load reduction quantity as menu options, a controllable load demand response menu pricing model taking minimum total cost of system power supply as an objective function is built, and the model is subjected to optimization solving to obtain an optimal controllable load demand response menu for the electric power users to select. According to the pricing method, the users with different risk preferences can be effectively distinguished, so that the autonomous selectivity of the users to the electricity price is improved, the positivity of user participation is enhanced, and optimization and configuration of electric power resources are easy to realize.

Description

technical field [0001] The invention relates to the technical field of smart grid optimization and coordination dispatching, in particular to a controllable load demand response menu pricing method considering user risk preference. Background technique [0002] With the continuous development of social economy, people's demand for electricity is also increasing year by year, and problems such as shortage of energy resources, energy crisis and environmental pollution have become increasingly prominent. At the same time, a large amount of intermittent renewable energy is connected to the power grid, which has a series of impacts on the safe and stable operation of the system, such as power imbalance. Therefore, how to make full use of a large number of controllable load resources on the demand side to participate in the dispatching operation management of the power grid has become an important direction of current power research. [0003] In the case of insufficient power gen...
