共享经济扰乱了住房和交通服务市场。房屋所有者在外出度假时可以出租他们的房产，车主可以提供拼车服务。这些共享经济商业模式是基于将未充分利用的基础设施货币化。它们通过将急切的卖家与有意的买家相匹配的点对点平台得以实现。在电力行业是否存在有吸引力的共享经济机会呢？在未来的智能电网中，哪些产品或服务可以被共享？我们首先探索电力行业的共享经济机会，并讨论这些机会面临的监管和技术障碍。然后我们研究企业共享其电力存储这一具体问题。我们描述了现货市场中共享存储的均衡价格。我们将企业的存储投资决策表述为一个非凸非合作博弈。我们表明，在一个温和的一致性条件下，存在一个纳什均衡，它是唯一的，并且它支持社会福利。我们讨论了电力实物交换所需的技术平台，以及电力存储交易所需的市场平台。最后我们用综合示例来说明我们的想法。
The sharing economy has upset the market for housing and transportation services. Homeowners can rent out their property when they are away on vacation, car owners can offer ridesharing services. These sharing economy business models are based on monetizing under-utilized infrastructure. They are enabled by peer-to-peer platforms that match eager sellers with willing buyers. Are there compelling sharing economy opportunities in the electricity sector? What products or services can be shared in tomorrow's smart grid? We begin by exploring sharing economy opportunities in the electricity sector, and discuss regulatory and technical obstacles to these opportunities. We then study the specific problem of a collection of firms sharing their electricity storage. We characterize equilibrium prices for shared storage in a spot market. We formulate storage investment decisions of the firms as a non-convex non-cooperative game. We show that under a mild alignment condition, a Nash equilibrium exists, it is unique, and it supports the social welfare. We discuss technology platforms necessary for the physical exchange of power, and market platforms necessary to trade electricity storage. We close with synthetic examples to illustrate our ideas.
