Embodiment Construction

[0060] The technical solution of the invention will be described in detail below in conjunction with the drawings.

[0061] Inverter air conditioner load aggregation control peak shaving method, divides the predicted daily load curve into time slices of equal length, carries out loop detection on each time slice, selects controllable air conditioners on the time slices that need to reduce load, and uses the temperature control of a single air conditioner Method to reduce the load. In dispatching, the power grid can choose to maximize the air conditioning load reduction potential or choose the most economical control scheme based on economic factors.

[0062] The distribution setting diagram of the aggregate controller is shown in Figure 1(a). In a smart grid community composed of J users, each user is equipped with an inverter air conditioner, and each air conditioner is equipped with an inverter that can be connected to the community The controller is the sub-controller for infor...

Abstract

The invention discloses an aggregation-control peak clipping method for variable-frequency air conditioner loads, and belongs to the technical field of power dispatching. According to the method, a predicted daily load curve is divided into time slices with equal spans, a beginning-end load of each time slice is taken as the load of the slice of time, a peak-value time slice is detected circularly, the beginning end of the peak-load time slice is taken as a midpoint in each circulation, a method for controlling the temperature of single air conditioner is adopted to control an air conditioner which has the largest clipping potential or the optimal economical efficiency, and the loads at the half time slices before and after a peak-value moment are reduced. According to the aggregation-control peak clipping method for the variable-frequency air conditioner loads, the method is simple, and under the condition that the comfort degree requirements of users are met, the peak clipping effect is remarkable.

Description

Technical field [0001] The invention discloses an aggregation control peak shaving method of inverter air conditioner load, and belongs to the technical field of power dispatch. Background technique [0002] With the rapid economic development, the demand for electricity is growing rapidly. In contrast, the construction of power facilities is obviously lagging behind, and social production and life require higher quality of power supply. Among them, the air-conditioning load accounts for a large proportion of the summer load peak. According to statistics, the air-conditioning load in East China accounts for more than 30% of the summer load peak, and it is even close to 50% in mega cities such as Beijing, Shanghai, Guangzhou and Shenzhen. The ever-increasing air-conditioning load causes the peak load in summer to rise continuously, causing power supply pressure, which is not conducive to the safe and stable operation of the power system. The concentration of air-conditioning use p...
