Problems solved by technology
However, with the substantial increase in wind power installed capacity, there has also been a more obvious problem of wind curtailment
In the first three quarters of 2017, China’s accumulative curtailment of wind power was 29.55TWh. Although it has decreased compared with the same period in 2016, the problem of wind curtailment in some provinces and regions is still very prominent
[0005] (1) The single form of central heating reduces the user's choice, and the indoor temperature cannot be adjusted remotely. When the user is not at home, the heating is supplied as usual, which not only causes energy waste, but also increases user expenses;
[0006] (2) The user cannot realize the complementarity of multiple energy sources, and cannot play the role of price adjustment. On the one hand, the wind is abandoned due to the insufficient peak-shaving capacity of the system, and on the other hand, central heating causes energy waste;
[0007] (3) Without considering the real-time price factors of electricity, gas and heat, it is difficult to promote the consumption of new energy and reduce carbon emissions through price tools

The invention relates to an indoor temperature control method and a control device for electric and thermal comprehensive heating, including an acquisition communication module, a cloud communication module, a control communication module, an operation display module, a data storage module and an execution calculation module. According to the obtained real-time electricity price, gas Price, central heating price, which energy form to use for heating through the heat source control method, and adjust the energy supply; Determine and control the energy input power of the hot water source and adjust the temperature of the hot water; determine the opening of the hot water outlet valve according to the set target room temperature and the real-time temperature data collected by the room temperature sensor, control the flow of hot water, and adjust the indoor temperature. The present invention comprehensively applies multiple forms of energy such as electricity, gas, and heat for heating, which can effectively reduce heating costs for users, reduce greenhouse gas emissions, and improve heating experience for users.
Description
technical field [0001] The invention belongs to the technical field of energy control, and in particular relates to an indoor temperature control method and a control device for electric heat integrated heating. Background technique [0002] In alpine regions, such as my country's three eastern provinces, Inner Mongolia and other regions, severe winters are long, heating is an essential material condition for urban residents to survive the winter, and it is an important livelihood project that affects the normal life and production and operation of residents. It is usually in the form of central heating, using coal as fuel to heat boiler hot water, which is transported to residential buildings through the pipe network, and the cold water is returned to the heating station after heat exchange. Central heating has the characteristics of large heating area and wide heating range. At the same time, it can effectively use the waste heat of thermal power plants and industrial ent...
