DR (Demand response) has an important role in electricity power market by reducing load quantity instead of increasing generation for balancing demand and supply. DR resources are regarded as an extra tool of balancing supply and demand in emergency condition. Also, DR resources can be used in normal condition or used for the purpose of maintaining the reserve rate. Because of the characteristics...
This paper reviews the design and operation of a number of large, regional organized markets in the US, as well as the operation of stand-alone single balancing area bilateral markets, from the viewpoint of integrating large amounts of variable output renewable energy sources. Significant differences between the two types of markets are noted. In addition, a series of shortcomings of the first generation...
Web based online real-time reliability integrated information system is asked rapidly for more efficiency and demand response in recent. As the utilization of renewable resources has been receiving considerable attention in recent years, the information system requirement is increased. Specially, the reliability information system is more important for implementing the smart grid. This paper describes...
The opportunities and challenges of implementing a smart electric supply system are discussed, including how to integrate the local public goods of electric system reliability, and increasingly of environmental compliance, in an efficient way. The full potential of the smart grid cannot be attained, however, without the wide-spread availability of real-time pricing for electricity so that all parties,...
ERCOT is transitioning from a current zonal market to a newly redesigned nodal market. In the new ERCOT nodal wholesale market, a Reliability Unit Commitment (RUC) process is designed and implemented to ensure transmission system reliability and security. The main objective of RUC is to ensure that enough resource capacity, in addition to ancillary service capacity, is committed in the right locations...
