"Renewable Energy Aggregation: A Coalitional Game Approach," by Pratyush Chakraborty

Aggregation of renewable energy resources has significant potential to reduce the cost of variability for renewable integration in a power grid. In this work, we focus on developing aggregation strategies using cooperative game theory. We consider two problems. In the first problem, renewable energy producers form a coalition to jointly bid in the two-settlement electricity market. We propose a contract that produces non-empty core and thus stability for the game of realized profit. Next the benevolent aggregator designs a strategy that improves their long-term profitability maintaining the short-term stability goals. In the second problem, we investigate the possibility of forming coalitions among consumers having rooftop photovoltaic solar cells under various incentive programs such as feed-in tariff, net metering, net purchase and sale. For net metering, and net purchase and sale, we develop a pricing condition under which the cooperative games have non-empty cores. In both the problems, we develop cost allocation rules that are based on the cost causation principle. Thus, our strategies strongly promote aggregation of renewable energy.
