Abstract

The increasing integration of solar photovoltaic (PV) systems and their generation variability has raised stability concerns with operators. Various Power Ramp Rate Control (PRRC) strategies are proposed to smooth out generation and maintain ramps below certain thresholds, but the cost of failing to do so remains unknown. This paper introduces a new metric to quantify the cost of excessive variability based on the energy these violations carry, which can be mapped to the grid ramping flexibility and serve as a penalty mechanism. This enables a coherent technoeconomic analysis of various forecasting- and battery-based PRRC alternatives. Results on a yearlong dataset with 1-second resolution identify the optimal battery size and show that invest-free forecasting-based approaches can also perform quite satisfactorily.
