The power grid is expected to experience a higher degree of intermittency and uncertainty both in generation and demand sides due to increasing uptake of solar PVs and EVs, which may result in overloading of the distribution network, and affect the grid stability, as well as the power quality [18-23].However, the coordinated operation of solar PV and EV charging can
2.1 Simplified Approach to Mathematical Modeling of Electrical Grid Stability with Renewable Energy Integration. A key aspect of electrical grid stability is the balance between generated power and consumed power [].If these two values are not in balance, the grid''s voltage and frequency can fluctuate, which can lead to instability [].To model this balance, we can use
