specific Embodiment

[0253] In particular, as figure 2 In this embodiment, a regional electric-thermal integrated energy system composed of an IEEE33 regional power system and a 51-node regional thermal system is selected, and its topology is as follows figure 2 shown. The system contains two energy stations. The equipment in each energy station includes Photovoltaic (PV), Solar Collector (SC), Gas Turbine Combined Heat and Power (CHP) unit, Electric Boiler (Electrical) boiler, EB). In this example, three typical days of winter (120 days, determined according to the heating period), transition season (153 days), and summer (92 days) are used to verify the solar energy absorption capacity evaluation model.

[0254] In this embodiment, four sets of calculation examples are selected to verify the solar energy absorption capacity evaluation model of the regional electric-thermal integrated energy system proposed in the present invention, to explore the optimal solar energy configuration and operat...

Abstract

The invention relates to a regional electric-thermal integrated energy system solar energy absorption capability assessment method, which comprises the following steps: firstly, determining a regional electric-thermal integrated energy system model; secondly, establishing a solar energy absorption capability evaluation index based on electric and thermal collaborative absorption; thirdly, establishing a solar energy absorption capability evaluation model of the regional electric-thermal integrated energy system by taking the maximum system absorption capability as a target; then, power distribution network system parameters, regional heat supply network parameters and regional electricity-heat integrated energy system equipment parameters are determined; and finally, solar energy consumption capability evaluation is carried out on the regional electric-thermal integrated energy system, and a system maximization consumption mode and corresponding reasonable configuration of solar energy consumption equipment are obtained. According to the invention, when the method is adopted to evaluate the solar energy consumption capability from the perspective of consumption technology, the regional electric-thermal integrated energy system can explore the own consumption capability, the consumption mode and the reasonable configuration of solar energy consumption equipment, and the maximum consumption of solar energy is realized.

Description

Technical field [0001] The present invention relates to a regional integrated energy system in the technical field of power systems, and in particular to a method for evaluating the solar energy absorption capacity of a regional electric-thermal integrated energy system. Background technique [0002] With the rapid development of economy, society and energy industry, the wave of promoting the development of renewable energy has swept across the world. As one of the most promising renewable energy sources, solar energy will play an important role in the future energy landscape. However, with the rapid growth of installed solar energy equipment, the problems of insufficient solar energy utilization, unreasonable consumption methods, and serious light abandonment have become increasingly prominent. Limiting the maximum consumption and utilization of solar energy. Solar energy consumption is affected by many factors such as the topology, operating characteristics, and coupling...
