The proposed research will develop short-term reliability models for renewable resources with smart grid technology application for electric power systems. The models will be embedded in new methodologies that will be developed to evaluate operating performance for efficient utilization of energy resources while maintaining acceptable level of system reliability. Widespread support for renewable energy has led to rapid increase in large-scale wind power integration in power systems. Significant growth in intermittent generation, increased transmission congestion with highly fluctuating severity levels, and the relative growth in distributed generation with potential wind and solar power are considerable changes in modern power systems. Increasing use of electric vehicles can bring about significant changes to energy use and management in future power systems. These changes have and will create new challenges to system operation in order to provide reliable and efficient use of electrical energy. Smart grid technology is receiving significant attention as potential means of mitigating these problems. The application of smart grid technology in various forms can significantly influence the energy demand profiles, response characteristics to system conditions, and operating philosophy. These transitions further dictate a need to deviate from the conventional practices of system operation, and research and develop new and suitable techniques considering the applications of emerging technologies and potential operational measures. The proposed research will develop methodologies, considering the ongoing system structural changes and initiatives, to increase energy efficiency, maximize renewable energy utilization and maintain acceptable reliability of the overall system. The objective is to provide useful indicators and valuable information to power system operators in order to maximize the benefits from different types of energy sources considering storage opportunities from electric vehicles and demand response initiatives in the changing environment. The developed methods should also be useful to energy policy makers and to system regulators to develop and implement appropriate reliability standards in the changing energy scenario.
