Impact of Solar Panels and Cooling Devices on Frequency Control after a Generation Loss Incident

Common household devices, such as solar panels and refrigerators, offer a considerable potential for frequency regulation, given their aggregate power generation and consumption. In this paper we present a simple approach to control the power contribution of a population of solar panels and thermostatically controlled loads, via a proportional control, in accordance with the current primary control practice. This control is suitable for a decentralized implementation. In addition, we consider the effect of renewables on the electricity network transfer function. We have tested the framework on a generation loss incident with different amount of solar power. Simulations display the capability of the control scheme and underline a chance of load shedding with a growing population of solar panels.
