Problems solved by technology

However, due to many factors affecting load changes and large fluctuations in grid load, the accuracy of power load forecasting, which is an important prerequisite and basis for grid planning, is usually not high.
However, there are still difficulties in how to quantify the effect of demand side management in power load forecasting

Embodiment Construction

[0049] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0050] Power grid planning is based on load forecasting and power supply planning to determine the corresponding grid wiring to meet the requirements of reliable, economical and flexible power transmission. Power grid planning determines when and where to invest in what type of transmission lines and the number of circuits to achieve the required transmission capacity within the planning cycle, and to minimize the cost of the transm...

Abstract

The invention discloses a power network load prediction method with demand side resources being taken into consideration. The method comprises the following steps: determining load prediction range of a substation; determining at least one kind of power terminal user connected to each feeder line of the substation within the load prediction range; determining at least one kind of demand side resource included in each type of power terminal user connected to each feeder line; calculating maximum load of each feeder line under the function of all demand side resources and within the predication time period; and carrying out accumulation on the calculated maximum loads of the feeder lines of the substation within the load prediction range, and then, multiply the accumulation value by load coincidence factor within the load prediction range to obtain a regional maximum load of the substation under the function of all demand side resources, within the predication time period and within the load prediction range. The invention also discloses a power network load prediction device with the demand side resources being taken into consideration.

Description

technical field [0001] The invention relates to the field of grid planning, in particular to a grid load forecasting method and device considering demand-side resources. Background technique [0002] As an important part of power system planning, power grid planning is a development plan for the grid structure of the power system based on the load and power supply development planning of the power system. It not only needs to meet the requirements of relevant power supply, but also coordinates the various components of the power system to make the whole system reasonable in structure and efficient in operation. With the increasing energy crisis and environmental pollution, as well as the basic national conditions of differences in the environmental carrying capacity of different regions in my country and the severe challenges faced by power grid enterprises, it is necessary to change the traditional power grid planning model. [0003] In recent years, demand-side management...
