Design of a phase-locked loop (PLL) for inverters that convert power from renewable energy sources into stable energy that can be used on the grid. 

By determining the optimal mix of energy sources, which are constantly changing due to weather conditions and other unpredictable factors, we aim to maximize economic benefits while ensuring a reliable power supply to consumers. 

Improving grid stability using Phasor Measurement Units (PMUs) to measure and provide accurate and synchronised data in real-time across large geographical areas. 

Implementing a controlled islanding strategy to limit the impact of cascading faults, where an event, such as a power outage, triggers a series of additional faults across the power grid, resulting in widespread disruptions. 

Damping of power system oscillations caused by factors such as power demand or variations in wind or solar output, by controlling set-points of the controllers for wind and solar plants.
