Summary:
Variable generation sources such as wind are being integrated into today's electricity systems and add more uncertainty to the system. Furthermore, demand peaks keep growing and the system must provide operating reserves for di®erent eventualities: variations in intermittent energy production and demand as well as failures in generation equipment.
A model will be used which is able to optimise the day-ahead unit commitment decisions and to simulate the real time reserve necessities.
This model includes a demand response option which enables demand to provide spinning reserves via automatic load response. Here demand is dispatched in a centralised approach. We will analyse which cost savings can be achieved with °exible demand for reserves, up to which point demand can provide system reserves and which generation technologies are replaced.
Demand may not be controlled centrally but may o®er demand variations in markets. Due to a minimum size, some agents can participate in those markets only through the aggregation of various agents in the form of a Virtual Power Plant (VPP). VPPs with various demands and distributed generations are analysed here. It will be studied how VPPs reduce uncertainty and how this in°uences reserve requirements and system operation.
