Abstract

Penetration of renewable energy such as wind and solar has been increasing rapidly in the grid. Due to intermittent properties of these sources, power generation cannot be scheduled as well as predicted easily. A sunny day can result in power variation from solar energy than predicted. Similarly, power generated from the wind power have different profile every day and can change in quick time. So excess generation from these renewable sources may result in over frequency problem in the network. Thus it has increased the necessity of frequency control reserves which can be activated instantaneously for stability of power network. This thesis deals with the potential of using heating energy required for house via electric space heater as frequency responsive reserves during excess generation from renewables. Daily heat loss from a house is calculated on hourly basis with respect to external temperature. Electric space heater stores the equivalent amount of heating energy to compensate loss during the off peak period when price of electricity is cheap. During excess generation from renewables, off peak storing of required heating energy is altered to instantaneous feeding to act as frequency reserves.
