Optimal Scheduling Considering Different Energy Hub Model of Integrated Energy System

Abstract

With the high penetration of wind energy, compared with traditional thermal power, it has the characteristics of clean, environmental protection and economy. However, wind energy has the characteristics of randomness, volatility and intermittence, which leads to serious wind abandonment. Due to the characteristics of wind energy, its utilization efficiency is low, resulting in a waste of resources. In order to solve this problem, this paper proposes the concept of energy hub (EH), which is a common modeling method in integrated energy system (IES). In this paper, three kinds of EH cases are constructed according to the coupling of different energy equipment. Through the coupling modeling of different types and quantities of energy equipment, the simulation calculation is carried out respectively to verify the impacts of different EH on system benefits and the effectiveness of the proposed model and method.
