Q: We are increasingly seeing the periodic oversupply of renewable energy at certain times of the day leading to negative power prices.  As the renewable supply ramps down in late afternoon, the resulting load curve appears graphically as the so-called duck curve with load continuing to peak.  Surprisingly, universal support does not exist for one potential solution for both of these problems, which is a proxy demand resource (PDR) such as some form of storage that the grid operator would call upon as needed.  Is there a better solution for the oversupply and imbalance issues?  If you believe in the PDR solution, how would you address the opposition?
