Impacts of renewable energy penetration on nodal price and nodal reliability in deregulated power system

The utilization of renewable sources in power generation and system deregulation are two major changes the power system are undertaking. Different evaluation models are needed in order to incorporate renewable generation in the existing power system analysis. In deregulated power system, the impacts of renewable generation penetration are not only on the physical operation, but also on economic operation. In this paper, the penetration of wind and solar power are investigated in a poolco market operation. The renewable generation is assumed to have the priority of being consumed over conventional generation. A new method which captures the chronological performance of enumeration reliability analysis has been proposed. The new method can also take into consideration of the time variant nature of renewable generation. The results of system with or without renewable generation are compared which shows the benefit bring by renewable generation in power market operation.
