我们的重点是扩展位置边际电价(LMP)原则，以(I)纳入实际和无功、线损、电压控制和配电资产寿命恶化的边际成本，以及(Ii)使配电网连接的负荷和发电机能够参与基于边际成本的实际和无功交易。为此，我们定义了一个配电市场，它可以动态地发现时空真实和无功电价，以优化分布式发电资产、用户、变压器和其他资产的成本和效用、寿命退化、线损和电压控制，同时观察完全交流潮流约束。我们解决了配电馈线上的社会最优日前市场(DAM)清理问题，配电馈线包括工业、商业和住宅支线，为传统的非弹性和灵活的可重新调度负载提供服务，并且具有能够利用相对于其主要用途的过剩容量来提供无功补偿和电压支持的设备。对几种大坝清理方案的数值结果阐明了一个功能齐全的配电市场在为分布式可再生发电和最后但并非最不重要的配电网络租金提供有效的运营激励、需求的跨期调度和最优位置信号方面的价值。
We focus on extending Locational Marginal Price (LMP) principles to (i) incorporate marginal costs of real and reactive power, line losses, voltage control, and distribution asset life degradation, and (ii) to enable distribution network connected loads and generators to participate in marginal cost based real and reactive power transactions. To this end, we define a distribution market that can discover spatiotemporal real and reactive power prices dynamically to optimize cost and utility of distributed generation assets, consumers, transformer and other asset life degradation, line losses, and voltage control, while observing full AC load flow constraints. We solve the socially optimal day-ahead market (DAM) clearing problem on a distribution feeder containing industrial, commercial and residential sub-feeders serving conventional non-elastic and flexible reschedulable loads and featuring devices capable of using excess capacity relative to their primary use to provide VAr compensation and voltage support. Numerical results on several DAM clearing scenarios elaborate the value of a fully functional distribution market in providing efficient operation incentives, intertemporal scheduling of demand and optimal location signals to distributed renewable generation and last but not least distribution network rent.
