**6. Conclusion**

Significant capacity of renewable generation resources operating online at any given time is of great concern to grid security due to the intermittent nature of many of the resources. On one hand, the potential volatility of the intermittent generation output could cause great stress on the system's generation planning and ramp management. On the other hand, these intermittent resources could be operating at locations that contribute to transmission line congestion and become very challenging problems for a lot of the RTOs.

This chapter addresses the challenges of renewable integration from a generation dispatch perspective. The framework of Smart Dispatch is proposed in which the applications of demand forecasting and robust dispatch are discussed in detail. A new dispatch system called Generation Control Application (GCA) is described to address the challenges posed by renewable energy integration. GCA aims at enhancing operators' forward-looking view under changing system conditions such as wind speed or other weather conditions. GCA provides operators with situation awareness of any potential abrupt ramping events or potential system imbalance and alerts operators in advance if any actions need to be taken. With dynamic and robust dispatch algorithm and flexible system configuration, the system provides adequate system ramping capability to cope with uncertain intermittent resources while maintaining system reliability in large grid operations.

Smart Dispatch is deemed critical for the success of efficient power system operations in the near future.
