The major subject of this talk is the introduction and testing of a new operating paradigm necessary for sustainable performance of the changing electric power industry. We first show that it is very difficult with today's software tools to balance power system supply and demand with large amount of variable resources due to their hard-to-forecast nature. This creates the need for fundamentally new algorithms in support of short-term forecast and flexible operation. We then propose a distributed look-ahead dispatch concept, which leverages (1) the near-term forecasts of intermittent wind generation, (2) flexibility in price responsive demand, and (3) the storage capabilities such as Plug-in Hybrid Electric Vehicles to participate into real-time energy balancing and frequency regulation services. Through an IEEE Reliability Test System example, we show that the proposed dispatch will lead to an overall cost-effective and environmentally benign utilization of the electric energy system portfolio in electricity markets. The proposed approach provides a theoretical framework for systematic integration of sustainable energy resources, such as wind and solar, with quantifiable performances.
