Electric heat storage device configuration system

Abstract

The invention provides an electric heat storage device configuration system. The system comprises a power grid, a voltage transformation device and a peak regulation system connected with the power grid, the peak regulation system comprises a solid electric heat storage device (3) and a liquid electric heat storage device (4), and when the solid electric heat storage device (3) and / or the liquid electric heat storage device (4) are / is started, an input voltage input to the solid electric heat storage device (3) and / or the liquid electric heat storage device (4) is increased to a specified voltage in a slope mode. The intelligent smooth deep peak regulation of a power grid is realized, the impact on the power grid is reduced, and both the heat supply livelihood guarantee and the power gridpeak regulation demand are met.

Description

[0001] This application is a divisional application for an invention patent application with an application date of January 23, 2017, an application number of 201710058624.2, and an invention title of "A System for Configuring an Electric Heat Storage Device". technical field [0002] The invention relates to the field of deep peak-shaving design of electric power, in particular to the field of scheme configuration design of an electric heat storage peak-shaving device of a cogeneration power plant. Background technique [0003] The combined heat and power units operate in the mode of "heating and power generation", and the peak regulation capacity is only about 10%. Difficulty in peak regulation has become the most prominent problem in power grid operation. If the contradiction between power grid peak regulation and thermal power unit heating is not properly handled, it may affect the safety of residents' heating in winter and affect people's livelihood. At present, cogene...

AI Technical Summary

Problems solved by technology

If a solid electric thermal storage device is simply used, since the power range cannot be adjusted, the peak-shaving capacity of the power plant unit cannot be deeply excavated, which will affect the overall economics of peak-shaving. However, due to the lack of heat storage function, it cannot meet the needs of residents for continuous heating in winter. Although some projects are equipped with hot water tank storage, due to the limited heat storage capacity of hot water tanks, it is difficult to meet the heating needs of large areas.
