Embodiment

[0147] Basic data:

[0148] The residential area IES is selected as the research object of the present invention. Take a typical summer day as an example to achieve optimal scheduling. In summer, cooling demand accounts for the largest proportion, while gas demand accounts for the smallest proportion. The operation period is 24 hours, and the optimal scheduling unit time is 1 hour. An operating cycle is divided into 6 cycles according to the electricity price. Peak hours include 10:00 to 15:00 and 18:00 to 21:00, and the electricity price is 0.82￥ / kWh. Normal hours include 7:00-10:00, 15:00-18:00, 21:00-24:00, and the electricity price is 0.53 ￥ / kWh. The valley period includes 0:00~7:00, and the electricity price is 0.25￥ / kWh. The price of natural gas is 2.5￥ / m3.

[0149] Case settings:

[0150] Case 1: The flexible load and virtual energy storage model are not considered; the room temperature is set to a fixed value of 26°C, and the water temperature is set to a fixed ...

comparative example 1 and 2

[0168] Comparing Cases 1 and 2, with the addition of flexible electric and gas load models, the total system operating cost is reduced by 2.43%. Comparing Cases 1 and 3, with the addition of flexible electric and gas loads and virtual energy storage models, the total system operating cost is reduced by 4.53%.

[0169] The present invention proposes a day-ahead optimal scheduling model based on an energy hub to reduce the operating cost of the IES. First, the virtual heating / cooling energy storage system is combined with the flexible electric / gas load model to realize the optimal operation of the IES and effectively reduce the operating cost of the IES. At the same time, a comprehensive satisfaction model based on comprehensive weighting method is proposed to quantify the satisfaction of energy consumption and reduce the capacity redundancy of IES equipment. Finally, a case study is carried out in the summer scene of a residential area. The results show that when the comprehens...

Abstract

The present invention relates to a community comprehensive energy system scheduling method considering comprehensive satisfaction, comprising the following steps: 1) combining the structure of the community comprehensive energy system and the demand response model to construct a community comprehensive energy system scheduling model considering the comprehensive satisfaction; 2) using Taking the comprehensive satisfaction as a constraint, the community comprehensive energy system dispatching model considering the comprehensive satisfaction is solved, and the optimal dispatching scheme with the lowest operating cost and satisfying the comprehensive satisfaction requirement is obtained, and the dispatching operation is carried out with this scheme. Compared with the prior art, the present invention has the advantages of reducing the energy consumption cost of the system, reducing the redundancy, and ensuring the satisfaction of energy consumption.

Description

technical field [0001] The invention relates to the field of optimal scheduling of energy systems, in particular to a community comprehensive energy system scheduling method considering comprehensive satisfaction. Background technique [0002] Excessive use of traditional fossil energy has caused continuous environmental pollution problems. Improving energy efficiency and reducing pollutant emissions have become important issues to be considered in modern energy systems. However, traditional power systems, thermal systems and natural gas systems are independent plans , designed and operated, this operating method ignores the coupling between different energy types and greatly limits the flexibility of the energy system. Therefore, the integrated energy system has become an important method to solve this problem. [0003] At present, there are many researches on the demand side management of IES. The regional power and heating multi-energy system based on combined heat and po...
