Abstract: Aggregation of geographically diverse renewable energy resources has significant potential to reduce the variability of renewable integration in a power grid. In this work, we focus on developing an aggregation strategy using cooperative game theory. It has been previously shown that using a joint power contract, the cooperative game of expected profit with renewable resources has a non-empty core. But we show that the game of realized profit has empty core using that contract. Here, we propose a new contract that generates non-empty core and thus stability for the game of realized profit. Next, we allocate the realized cost of variability. The allocation is based on
cost causation principle and has a simple formula. Finally we propose a strategy taken by the benevolent aggregator that will enable the resources to maintain their short-term term stability goals of aggregation as well as improve the long-term profit. Thus our strategy strongly promotes market aggregation of renewable energy.
