考虑网络约束和市场力限制的能源共享机制

An Energy Sharing Mechanism Considering Network Constraints and Market Power Limitation

Yue Chen, Changhong Zhao, Steven H. Low, Adam Wierman

摘要:

随着拥有分布式能源(DER)的产消者数量的增长,传统的集中式运营方案可能会受到利益冲突、隐私问题和激励不足的影响。在本文中,我们提出了一个能源共享机制,以解决上述挑战。它考虑了网络约束和产消者之间的公平性。在所提出的能源共享市场中,所有的产消者都在进行广义纳什博弈。证明了市场均衡在大市场或变分均衡时具有良好的特征。为了应对一般情况下可能出现的市场失灵、无效率或不稳定性,我们引入了一种价格管制政策来避免市场力的利用。改进的价格管制的能源共享机制可以保证社会近优市场均衡的存在性和唯一性。一些有利的性质,如生产消费者的个人理性,一个共享的价格结构类似的位置边际价格,并趋向于社会最优的生产消费者的数量增加。为了便于实现,给出了一种实用的投标算法,并给出了收敛条件.实验结果验证了理论分析的正确性,证明了该模型和方法的实用性.

英文摘要:

As the number of prosumers with distributed energy resources (DERs) grows, the conventional centralized operation scheme may suffer from conflicting interests, privacy concerns, and incentive inadequacy. In this paper, we propose an energy sharing mechanism to address the above challenges. It takes into account network constraints and fairness among prosumers. In the proposed energy sharing market, all prosumers play a generalized Nash game. The market equilibrium is proved to have nice features in a large market or when it is a variational equilibrium. To deal with the possible market failure, inefficiency, or instability in general cases, we introduce a price regulation policy to avoid market power exploitation. The improved energy sharing mechanism with price regulation can guarantee existence and uniqueness of a socially near-optimal market equilibrium. Some advantageous properties are proved, such as prosumer's individual rationality, a sharing price structure similar to the locational marginal price, and the tendency towards social optimum with an increasing number of prosumers. For implementation, a practical bidding algorithm is developed with convergence condition. Experimental results validate the theoretical outcomes and show the practicability of our model and method.
