Energy Sharing Design in a Prosumer Era
Abstract
The proliferation of distributed generation enables traditional consumers to produce energy. The integration of multiple energy carriers and facilities is reshaping our energy system from a highly regulated, operator-controlled network into a sophisticated social-interactive infrastructure with strategic agents competing for the supply and demand. Since the centralized operation approach does not allow each individual to act upon its profit-seeking nature, it no longer well fits the profound transition to the prosumer era. Market, as an invisible hand, is a promising tool for managing resources more efficiently. Inspired by the sharing economy in other sectors, we may want to ask: can energy be shared in a similar way? We explore the potential of energy sharing by answering why, how, and what if. For why, three typical approaches, i.e., self-sufficiency, sharing, centralized operation, are compared under a stochastic framework with uncertain loads, and sharing stands out for the fact that it can achieve a nearly social optimal efficiency in a distributed manner. For how, we design effective mechanisms for sharing among node-level and networked prosumers, respectively. Several desirable properties of the sharing market equilibrium are proved theoretically. We also develop a bidding process for implementation with proof of its convergence under mild conditions. For what if, a two-stage robust economic dispatch problem is used as an example, by replacing the centralized real-time operation with a distributed sharing scheme. It has been proved that the flexibility of the system is retained with only slightly sacrifice of economy. These works reveal fundamental understandings that facilitate in-depth analyses and design of the future energy sharing market.
