Embodiment Construction

[0111] The invention will be described in detail below with reference to the accompanying drawings and examples.

[0112] like figure 1 As shown, the integrated energy system can include a renewable energy power generation equipment such as wind power, photovoltaic power generation; energy storage devices such as battery energy storage equipment, gas storage equipment, energy conversion equipment such as CHP energy station, gas boiler, P2G, and electric load, heat Loads, these devices are constructed by grid, gas network, and hot networks.

[0113] like image 3 As shown, the output is input to the recent economic scheduling algorithm. Depend on image 3It can be seen that the input data includes a recent electric price curve, grid operation information, gas price, weather data, etc., and historical operation data. After the short-term prediction algorithm, the mixed integer optimization algorithm is calculated, and the output result is finally obtained, that is, the output of each ...

Abstract

The present invention relates to a method and system for a day-ahead economic scheduling of an integrated energy system. Firstly, the wind power, photovoltaic power generation, electric load and heat load of the integrated energy system are predicted to obtain the day-ahead forecast curve, that is, the forecast result; Optimize the objectives and constraints, so as to perform day-ahead optimization, and obtain the output of each CHP energy station, battery energy storage system, gas boiler output, and control instructions for P2G equipment in the integrated energy system. The invention improves operation flexibility and renewable energy consumption capacity.

Description

Technical field [0001] The present invention relates to a comprehensive economic scheduling method and system, which is a comprehensive energy system, which belongs to the technical field of new energy generator sets. Background technique [0002] With the development of new energy technology, the penetration rate of renewable energy is continuously improved and the continuous improvement of load demand, users are increasing in terms of energy network reliability and flexibility. Renewable energy power generation such as wind power, photovoltaic, has high uncertainty and intermittent, abandoned wind, abandoned light, and other problems. [0003] Although distributed power generation and hot and cold electric cogeneration have been widely promoted, there are also many problems, such as high-alone access grid costs and difficulties. In order to better solve problems and contradictions between distributed power supplies and grids, give full play to its characteristics and advantages...
