Combined heat and power generation central heating system with heat supply network side coupled with electric thermal storage peak regulation and operation method

Abstract

The invention discloses a combined heat and power generation central heating system with the heat supply network side coupled with electric thermal storage peak regulation and an operation method. Thecombined heat and power generation central heating system comprises a turbine, a condenser, a hot supply network initial station, a circulating pump, a near end heat exchange station, a far end heatexchange station, a hot water thermal storage tank, an electrically heated boiler, near end heat users and far end heat users. The near end heat exchange station and the far end heat exchange stationare connected in series or in parallel. The near end heat users and the far end heat users are connected in series or in parallel. The far end heat exchange station is arranged at the tail end of a primary network, and the far end heat users are arranged at the tail end of a secondary network. The far end heat exchange station is provided with an electric thermal storage system. The far end heat users are provided with electric thermal storage systems. According to the combined heat and power generation central heating system, power grid electricity peak regulation and the combined heat and power generation central heating system are coupled, power grid side electricity peak regulation is achieved, and the problem that heat supply to the tail end user in a combined heat and power generation heat supply network is excessively insufficient is solved at the same time; and in this way, the combined heat and power generation central heating system guarantees the civil heating demand, has remarkable economic and social benefits and has great practical value.

Description

technical field [0001] The invention belongs to the field of centralized heat supply of combined heat and power technology, and specifically relates to a combined heat and power centralized heating system and an operating method used for peak regulation of electric heat storage coupled with heat network side. Background technique [0002] At present, the role of clean energy substitution of new energy is becoming increasingly prominent. However, wind power and photovoltaics have strong randomness, intermittency, uncontrollability, and anti-peaking characteristics, which gradually increase the difficulty of thermal power units in power grid peaking. In order to effectively consume new energy resources, the country has gradually increased the policy requirements for peak regulation of thermal power units. For example, the Northeast Supervision Bureau of the National Energy Relevant institutional support has been given to promote the consumption of clean energy through mechani...
