促进者是一种中介机构，向可再生能源生产者和消费者提供固定价格合同，并作为其平衡责任方，管理市场中的剩余不平衡。将不完全相关的剩余进行汇总可以抵消消费者的不平衡，并降低投资组合的总不平衡成本，但引发了一个分配问题：这些节省应如何在异质消费者之间分配？我们将此问题表述为一个合作博弈，即不平衡抵消博弈，并在两价不平衡结算机制下，从计算需求、预算平衡、群体理性和可加性四个方面比较了六种分配机制。我们建立了三个分析结果：边际成本贡献机制的预算平衡的充要条件，边际成本贡献机制和维克里-克拉克-格罗夫斯机制的群体理性，以及盖特利点良定义的充要条件。在丹麦2024年19个消费者的数据上，聚合将不平衡成本降低了10%，但这些节省的分配方式强烈依赖于分配规则。按消费量比例分配的固定费率分配（作为社会化不平衡定价的基准）向某些消费者收取的费用超过其独立成本的两倍，而所研究的所有博弈论机制在实践中都产生了稳定的分配。
英文摘要
A facilitator is an intermediary that offers renewable producers and consumers fixed-price contracts and, acting as their balance responsible party, manages the residual imbalances in the market. Pooling imperfectly correlated residuals nets consumers' imbalances and reduces the portfolio's total imbalance cost, but raises an allocation question: how should these savings be divided among heterogeneous consumers? We formulate this as a cooperative game, the imbalance netting game, and compare six allocation mechanisms under a two-price imbalance settlement in terms of computational requirements, budget balance, group rationality, and additivity. We establish three analytical results: a necessary and sufficient condition for budget balance of the marginal cost contribution mechanism, group rationality of the marginal cost contribution and Vickrey-Clarke-Groves mechanisms, and a necessary and sufficient condition for when the Gately point is well-defined. On Danish 2024 data for 19 consumers, aggregation reduces imbalance cost by 10%, but how these savings are shared depends strongly on the allocation rule. A flat-rate allocation proportional to consumption, used as a benchmark for socialized imbalance pricing, charges some consumers more than twice their standalone cost, whereas all the game-theoretic mechanisms studied produce stable allocations in practice.
