Description

technical field [0001] The invention relates to a microgrid scheduling method. In particular, it relates to an industrial park micro-grid electric-heat joint scheduling method based on distributed clean heating, which is suitable for the day-ahead scheduling work of energy suppliers in industrial parks. Background technique [0002] With the development of the energy Internet, the coordinated supply of electricity / heat / gas has become an inevitable trend of future energy supply. Due to its clean and efficient energy supply characteristics, electricity / heat / gas combined supply has many applications in new industrial parks, but it also brings a series of problems. On the one hand, the park has space resources for building a large number of photovoltaic and other new energy power generation equipment and the load is relatively concentrated, which is conducive to solving the problems of poor investment returns and high energy loss caused by long-distance power supply, but it inc...

Problems solved by technology

[0004] However, there are certain limitations in the currently commonly used dispatching method of electricity and heat combined dispatching to accommodate new energy.

First, the scheduling method is mainly suitable for energy supply systems dominated by cogeneration units. It mainly uses the idea of ​​decoupling electric heating to expand the consumption space for new energy, but it is difficult to apply to the use of distributed clean heating equipment for heat supply. The system, distributed heating and heat storage devices are distributed in each building with heating demand, which can be flexibly adjusted according to the characteristics of the building, and can participate in the consumption of new energy itself; second, it is difficult to express the heat demand with a fixed curve Considering the indoor temperature, in fact, the change of indoor temperature is an important parameter of the heating system, which can reflect the quality of heating and the comfort of users
