Optimal Schedule Strategy of Integrated Energy System Considering Static Voltage Stability

The optimization operation of integrated energy system is to achieve coordination between different energy systems such as electricity, heating, cooling, gas, etc. The purpose is to achieve the goals of improving energy efficiency and reduce energy costs and environmental pollution. At present, most relevant studies only consider the operational constraints of various types of equipment, and do not consider network constraints. In this paper, the static voltage stability in the power system is taken into consideration. An optimized scheduling method for integrated energy system operation considering the constraints of the power network is proposed. Simulation examples of the integrated energy system based on the IEEE 13 standard node expansion are verified by simulation. The results show that the proposed method can further promote the global optimization of the integrated energy system.
