Abstract

The invention belongs to the technical field of intelligent power grids, and particularly relates to an air conditioner time-sharing scheduling method based on demand response. The air conditioner time-sharing scheduling method based on demand response includes the steps that a power supply operator installs photovoltaic power generation devices connected to the grid for users; the users are classified into two categories according to the temperature variation ranges set for air conditioners by the users, and the users form an alliance along with the photovoltaic power generation devices; the photovoltaic power generation quantity, the baseline load, the power grid power price, the indoor temperature, the outdoor temperature and the rated power of the air conditioners at the current time are obtained; according to the different time periods of the summit time, the flat time and the low tide time of the current power grid power price, the indoor temperature and the outdoor temperature, and in combination with the current photovoltaic power generation quantity, the start and stop of the air conditioners are controlled; the profits gained by the alliance are calculated, the contribution of the two categories of users and the photovoltaic power generation devices to the profits of the alliance is quantified through a Sharpley value method and the profits are distributed. The air conditioner time-sharing scheduling method based on demand response effectively improves the profits of the users and elimination of the photovoltaic resources on the spot, is low in time complexity and low in calculation cost and can be easily achieved on the user side.

Description

technical field

[0001] The invention belongs to the technical field of smart grids, and in particular relates to a method for time-sharing scheduling of air conditioners based on demand response. Background technique

[0002] Demand response technology refers to the market participation behavior in which users respond to electricity price signals or incentive mechanisms and adjust normal electricity consumption patterns. Introducing demand response technology on the user side, mobilizing the enthusiasm of the demand side to participate in the market through market prices or incentive mechanisms, and integrating comprehensive resources between the power supply side and the power consumption side are inevitable trends in the future development of the electricity market. In incentive-based demand response, the incentive mechanism acts as an intermediate factor to guide users to reduce load in time. The representative control method is direct load control. This method can simp...

Embodiment Construction

[0019] The embodiments will be described in detail below in conjunction with the accompanying drawings. The invention proposes a method for time-sharing scheduling of air conditioners based on demand response. figure 1 It is a structural diagram of the system, mainly composed of commercial users, photovoltaic power generation units, central controller and other elements. Among them, the load of each user mainly includes the load of air conditioners and other electrical appliances. The central controller will collect the energy information of each unit, and directly control the start and stop of each user's air conditioner, so that the electricity cost of the entire alliance is the lowest. Operators purchase and install photovoltaic power generation devices for users, and make profits through policy subsidies for photovoltaic power generation and income from alliances. The load is powered by photovoltaic power generation first. When the total load in the community is greater...
