Modern Power System Stability and Optimal Operating

Dear Colleagues,

The integration of renewable resources and electric vehicles into power systems presents significant challenges in power grids with respect to stability and operation, as they are accompanied by complex uncertainties.

Unlike traditional power resources, which are operated to match the demand of the loads, renewable resources (e.g., PV, wind) are usually controlled to extract the maximal available power along with the corresponding solar radiation intensity and wind speed, thus resulting in uncertainties of grid power sources. Similarly, the vigorous promotion of electric vehicles by the government has spurred huge changes in power load structure, increasing the number of load categories and complicating the characteristic differences among power loads. Note that both of these may introduce complex uncertainties into power systems, making it difficult to ensure modern power system stability and operation using traditional technologies. To guarantee the stability and robust operation of modern power systems, it is still necessary to presuppose the effective handling of uncertainties and new characteristics due to the large-scale integration of renewable resources, inverters and varied load behavior. Therefore, addressing the aforementioned challenges has been one of the most exciting research topics in modern power systems, benefiting power system stability, safety, and reliability as well as supporting their economical and efficient operation.

This Special Issue welcomes the submission of both original research and review articles related to the above topics, particularly including but not limited to the following fields:

• Stability analysis and optimal operation with respect to uncertainties;
• Stability analysis and optimal operation based on data-driven and AI methods;
• Robust stability control strategy and operating decision for varied conditions;
• Renewable generation system control strategies;
• Optimal operation of integrated energy systems;
• Modeling of the power systems with integrated renewable energy sources and varied loads;
• Analysis and modeling of renewable generation systems and load behavior;
• The influence of demand-side responses and management on power system stability and operation;
• Probabilistic analysis for modern power systems;
• Wide-band oscillation and its stability control strategy;
• State estimation frameworks for uncertain sources and loads integrated power systems.
