Problems solved by technology

In the power dispatching process of the power grid, the substation usually allocates the power of the power grid according to the power demand of the power consumption side. There are large differences in electricity consumption data. Although currently roughly divided into peak periods and low periods of electricity consumption and set different electricity charges to encourage users to self-adjust power allocation, the effect is limited, and it is not possible to determine the peak and valley periods of electricity consumption. play a good role in regulating

Embodiment approach

[0043] As an implementation mode, according to the power grid power consumption data, extreme power consumption peak periods and power consumption trough periods include:

[0044] According to the chronological order, connect the collected power consumption data of the power grid to form a power consumption curve;

[0045] Obtain the median point in the electricity consumption curve, and record the electricity consumption data of the median point as the standard electricity consumption data;

[0046] The interval higher than the median point on the electricity consumption curve is recorded as the peak interval of electricity consumption, and the interval lower than the median point on the electricity consumption curve is recorded as the valley interval of electricity consumption;

[0047] The time period corresponding to the peak power consumption interval is recorded as the peak power consumption period, and the time period corresponding to the low power consumption interval ...

Abstract

The invention discloses a comprehensive energy system power dispatching method and system. An energy storage station is arranged in a comprehensive energy system; in a power grid off-peak period and the electric quantity of the energy storage station is relatively low, the energy storage station stores redundant electric energy of the power grid. When the power grid is in a peak period, the storedelectric energy is discharged to the voltage transformation station and is distributed to the power utilization side through the voltage transformation station, the utilization rate of the electric energy in the power grid can be improved, and the power utilization cost can be saved and the economic benefit can be improved due to low electricity price in a valley period of the power grid and highelectricity price in the peak period of the power grid.

Description

technical field [0001] The present invention relates to the field of power grid power scheduling technology energy, in particular to a power scheduling method and system for an integrated energy system. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. In the power dispatching process of the power grid, the substation usually allocates the power of the power grid according to the power demand of the power consumption side. There are large differences in electricity consumption data. Although currently roughly divided into peak periods and low periods of electricity consumption and set different electricity charges to encourage users to self-adjust power allocation, the effect is limited, and it is not possible to determine the peak and valley periods of electricity consumption. It plays a very good regulating role. Contents of the invention [0003] In vie...
