Abstract

The invention relates to a thermoelectric decoupling and peak shaving system. The thermoelectric decoupling and peak shaving system comprises a thermal power plant heating-extracting heat supply network heating system and a heat supply network system. The thermoelectric decoupling and peak shaving system is characterized by further comprising an electric network and electric plant peak shaving control platform and a heat supply network heat storage and release operation and management platform and further comprising at least one of a circulating water waste-heat heat pump recycling system and an electric boiler heating system; and when the electric network and electric plant peak shaving control platform of the thermoelectric decoupling and peak shaving system gives out a peak shaving command, an electric plant converts electric energy into heat energy by starting an electric boiler and the circulating water heat pump and conveys the heat energy into a heat supply pipe network, and the heat supply network heat storage and release control platform is used for controlling the whole temperature increase of a primary pipe network and a secondary pipe network so as to achieve the purpose of pipe network heat storage. The wind abandoning and light abandoning peak shaving electric quantity is absorbed through the heat pump and the electric boiler, the complete thermoelectric decoupling can be achieved for the thermal power plant, the pure condensing operation depth peak shaving of the thermal power plant becomes possible, the thermal power plant can receive the subsidy through the depth peak shaving, and the heating safety can be guaranteed through the pipe network heat storage.

Description

technical field [0001] The invention relates to the field of utilization of pipe network energy storage and deep peak regulation of power grids, in particular to the field of deep peak regulation of electric loads realized by using electric boilers and heat pumps in thermal power plants through pipe network heat storage in winter. Background technique [0002] In China's three northern regions, the power market has ample capacity, gas turbines, pumped storage and other peak-adjustable power sources are scarce, the contradiction between power grid peak-shaving and the flexibility of thermal power units is prominent, and the grid's ability to accommodate new energy sources such as wind power, photovoltaics, and nuclear power is insufficient , the phenomenon of abandoning wind and light is serious. In order to solve these problems, the Northeast Electricity Regulatory Bureau issued the Northeast Power Ancillary Service Trading Rules. With the implementation of this policy, more...
