Enabling Extended-Term Simulation of Power Systems with High Photovoltaics Penetration

closed

This project aims to advance the understanding of the grid impact of high penetration of photovoltaic (PV) generation. The project will focus on development of novel numerical methods to solve the differential algebraic equations that define power systems. The project will implement variable time step methods to enable simulation of both slow and fast dynamics that define the low-inertia, high renewable penetration grid of the future. This will overcome the limitations of current software packages namely, that they only consider fast dynamics over brief time periods. By developing numerical methods to advance the power industry's understanding of grid behavior in high PV penetration grids, barriers to the proliferation of high PV penetration will be eased.
