Abstract
Aiming at the problem of source-load incoordination of combined heat and power (CHP) system caused by the high electro-thermal coupling strength, a optimal operation strategy of combined heat and power system based on electric thermal storage boiler and thermal inertia is proposed. Firstly, the internal heat transfer model of the solid electric thermal storage boiler was studied, and the three-dimensional numerical simulation of the temperature field of the thermal storage body was performed. Then, the thermal inertia model of the heating network and the building is established. On this basis, a coordinated optimization model of CHP system based on thermal storage boiler and thermal inertia is established with the goal of minimizing the operating cost of the system. The results show that the optimization strategy proposed in this paper can effectively reduce the electro-thermal coupling strength and improve the flexibility and economy of the CHP system.
Highlights
With the development of human society and gradual exhaustion fossil energy, various sectors of society have carried out many researches on the sustainable use of energy from the aspects of resources development and energy saving [1]–[3]
The actual physical model characteristics of the solid electric heat storage boiler were studied, and its thermal inertia was matched with the thermal inertia of the heating pipe network and the building, which could effectively improve the adjustment flexibility of combined heat and power (CHP) system and reduce the economic cost, being significant for coordinated operation of multi-energy systems under the ubiquitous Internet of Things
The thermal inertia in this paper focused on the thermal inertia of heating pipe networks and buildings
Summary
With the development of human society and gradual exhaustion fossil energy, various sectors of society have carried out many researches on the sustainable use of energy from the aspects of resources development and energy saving [1]–[3]. Based on the thermal inertia model of electric heat storage boiler, thermal pipe network and building, the coordination optimization operation strategy considering interia of heating system was proposed.
