Indoor temperature control method for comprehensive heating of electricity, gas and heat and control device

Abstract

The invention relates to an indoor temperature control method for comprehensive heating of electricity, gas and heat and a control device. The control device comprises an acquisition and communication module, a cloud communication module, a control communication module, an operation display module, a data storage module, and an execution operation module; which energy form is selected for heating through a heat source control method according to the acquired real-time electricity price, gas price and central heating price, and energy supply is adjusted; the energy input power of a hot water source is determined and controlled according to the acquired outdoor air temperature, the opening of a hot water outlet valve, the measured water temperature of the hot water source, the manually set target water temperature and the selected energy type, and the temperature of hot water is adjusted; and the opening of the hot water outlet valve is determined according to the set target room temperature and the real-time temperature data acquired by a room temperature sensor, the flow of the hot water is controlled, and the indoor temperature is adjusted. According to the indoor temperature control method and the control device, multiple energy forms of electricity, gas and heat are comprehensively applied for heating, so that the heating cost of a user can be effectively reduced, greenhouse gas emission is reduced, and the heating experience of the user is improved.

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 and thermal comprehensive heating. Background technique [0002] In alpine regions, such as the three northeastern provinces and Inner Mongolia in China, the severe winter season is long, and heating is a necessary 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. Usually in the form of central heating, coal is used as fuel to heat the hot water in the boiler, which is transported to residential buildings through the pipe network, and the cold water returns to the heating station after heat exchange. Central heating has the typical characteristics of large heating area and wide heating range. At the same time, it can effectively utilize the waste heat of thermal powe...

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
