The operations and planning rules for integrating variable resources aren’t the same across the electric power industry in the United States at present. Opinions are somewhat divided about what...
3Rs for Power And Demand
Dynamic monitoring and decision systems maximize energy resources.
is key to the clean and cost-effective use of wind and responsive demand. The implementation of self-commitment would require a transformation of today’s SCADA systems into multi-directional, multi-layered interactive dynamic monitoring and decision systems (DYMONDS). However, if this is done systematically, at least the first generation DYMONDS would be a natural outgrowth of today’s SCADA, and wouldn’t require a major re-design. Today’s SCADA would have to be enhanced by interactive multi-directional information exchange between system operators, aggregators of variable resources (such as wind, solar and demand) and the resources themselves. The NIST standards and protocols under design must enable minimal information exchange from the system operators to the aggregators and resources, in both directions and multi-laterally. An IEEE test system has shown that this system is capable of integrating greater than 50 percent wind capacity with less than 3 percent demand elasticity during most hours, while observing the same transmission limits. Symmetric distributed risk management is beneficial for all industry participants as their value is aligned with what they are compensated for.
