Abstract

The invention provides a peak regulation heat supply system with a heat storage function and a control method. The peak regulation heat supply system comprises an electric heating furnace (1), an energy storage system (2), a heat supply system (3), a first regulating valve (5) and a second regulating valve (6). A heat-transfer medium outlet of the electric heating furnace (1) is connected to the energy storage system (2) and the heat supply system (3) by the first regulating valve (5) and the second regulating valve (6) via pipelines. According to the peak regulation heat supply system, through structural design, valley electricity can be fully used in the application of the peak regulation heat supply system with the heat storage function, peak shaving and valley filling are conducted on a power grid, thus the resource utilization ratio of electrical equipment is increased, operation of the power grid is stabilized, energy storage cost is reduced greatly, and accordingly large-scale valley electricity utilization is made to be possible.

Description

technical field [0001] The invention relates to energy storage technology, in particular to a peak-shaving heating system with heat storage and a control method. Background technique [0002] In recent years, with the improvement of people's living standards and the rapid growth of power load, the peak-to-valley difference of power grid load has gradually increased. The problem of peak shaving is more prominent, and it also causes a series of difficulties for power dispatching. The power supply and power transmission and distribution equipment in the power system are planned and constructed according to the peak load of the power grid, but the duration of the peak load of the power grid is short, resulting in a low utilization rate of power equipment assets planned and constructed to meet the peak load demand. Researching and solving the problem of power grid peak regulation and improving asset utilization is an important issue facing power grid construction at this stage. ...
