Embodiment
[0071] In a specific example of the present invention, a small-scale IES comprehensive energy day-ahead scheduling method is disclosed, and the proposed scheduling model is verified. like figure 1 As shown, the model includes 6 grid nodes and 6 grid nodes. The system is connected to the main grid through tie lines. The system includes a 2MW CHP unit, a 1MW fan, and a 0.5MW electric heat pump. Node 4, Node 5 and Node 6 are residential building heating and power supply load nodes. The day-ahead forecast data of residential electricity load and wind power are as follows: figure 2 shown.
[0072] Import the day-ahead forecast data of residential electricity load and wind power into the established scheduling model, and use YALMIP to call CPLEX and other solvers to solve the problem, and obtain the power purchased by the main network, wind power, CHP unit output, and the power stored and released by the battery pack, such as image 3 shown. The detailed composition of the obta...

The invention relates to an integrated energy system day-ahead scheduling method considering a stepped carbon transaction and a renewable energy source forestation system. The method comprises the following steps: firstly, establishing transaction cost and constraint conditions about a stepped carbon price and renewable energy source forestation system; secondly, establishing a day-ahead scheduling model of the electric-thermal integrated energy system, and meanwhile, recording the transaction cost and constraint conditions about the stepped carbon price and renewable energy source forehead system into the model; secondly, converting the established scheduling model into a mixed integer linear scheduling model by using piecewise linearization; optimally, the day-ahead prediction data of the resident electric load and the wind power are imported into the mixed integer linear scheduling model, the model is solved by calling the CPLEX through YALMIP, and a day-ahead scheduling result of the integrated energy system is obtained.
Description
technical field [0001] The invention relates to the field of integrated energy scheduling, in particular to a day-ahead scheduling method for an integrated energy system. Background technique [0002] Promoting the tight coupling of the integrated energy system (IES), reducing the consumption of fossil fuels, and increasing the proportion of access to clean energy have become the common reform goals of all countries in the world. There are many energy interaction devices in the integrated energy system, which provide the possibility for the complementary advantages of various energy systems. Therefore, the integrated energy system has become the focus of energy research. Under the current situation in our country, it is necessary to vigorously develop clean energy and achieve double carbon targets. Under this goal, the optimization research of IES gradually shifts from traditional economic dispatch to low-carbon economic dispatch. [0003] At present, there have been exten...
