Control method for optimizing thermal power peak shaving through battery energy storage coordinated electric heating

Abstract

The invention discloses a control method for optimizing thermal power peak shaving through battery energy storage coordinated electric heating. In one embodiment of the invention, the control method comprises the following steps: in a peak period, judging whether the SOC (state of charge) of a battery energy storage system is greater than a preset SOC minimum value or not; if the SOC of the battery energy storage system is greater than the preset SOC minimum value, controlling a heat storage device to execute a heat release action to meet the thermal load demand, and controlling the battery energy storage system to discharge to increase the peak-valley price difference income; and if the SOC of the battery energy storage system is smaller than or equal to the SOC minimum value, controllingthe heat storage device to execute a heat release action to meet the heat load requirement, and meanwhile, controlling the battery energy storage system not to act. According to the embodiment of theinvention, by arranging a heat storage type electric boiler, the electric quantity can be consumed, and heat can be supplied in the heating period.

Description

technical field [0001] The invention relates to the technical field of energy management, in particular to a control method for coordinating electric heating with battery energy storage and optimizing thermal power peak regulation. Background technique [0002] my country's energy distribution and electricity load are reversely distributed, and the grid structure and power supply ratio are different in different regions. my country's "three north" regions are rich in wind energy and suitable for large-scale development of wind power generation. However, with the rapid development of wind power, the problem of wind power acceptance has become increasingly prominent. In my country's "Three North" areas, the heat load is high and the electricity load is low. During the winter heating period, the operation mode of the cogeneration heating unit leads to the contradiction between heating supply and peak regulation, which reduces the flexibility of the system and further aggravates...

In my country's "Three North" areas, the heat load is high and the electricity load is low. During the winter heating period, the operation mode of the cogeneration heating unit leads to the contradiction between heating supply and peak regulation, which reduces the flexibility of the system and further aggravates the problem of wind curtailment.
