摘 要：The rapid growth in energy demand with renewable energy sources (RESs) are presenting serious challenges for the optimal operation of power systems. The future perspective of the dramatic increase in RESs, such as wind and solar energy, may lead to severe problems related to power system stability. For this solution, the authors have developed the power supply and demand management system that is robust to instability. RESs are also connected to the existing bulk power systems via power electronics devices such as power conditioning systems (PCSs). However, when a large amount of RESs are interconnected in power systems, the level of power synchronization with power system may decrease. In this paper, we propose the novel control scheme of voltage source pulse width modulation (PWM) inverters for improving power system stability under future environment with uncertainties.
