An increasing concern in power systems is how to elicit flexibilities in demand, which leads to nontraditional electricity products for accommodating loads of different flexibility levels. We have proposed Multiple-Arrival Multiple-Deadline (MAMD) differentiated energy services for the flexible loads which require constant power for specified durations. Such loads are indifferent to the actual power delivery time as long as the duration requirements are satisfied between the specified arrival times and deadlines. The focus of this paper is the market implementation of such services. In a forward market, we establish the existence of an efficient competitive equilibrium to verify the economic feasibility, which implies that selfish market participants can attain the maximum social welfare in a distributed manner. We also show the strengths of the MAMD services by simulation.

电力系统中越来越引起人们关注的是如何激发需求的灵活性，这导致了非传统的电力产品可以适应不同灵活性级别的负载。我们已针对需要在指定持续时间内提供恒定功率的柔性负载，提出了多到达多期限（MAMD）差异化能源服务。只要在指定的到达时间和最后期限之间满足持续时间要求，这些负载就与实际的功率传输时间无关。本文的重点是此类服务的市场实施。在远期市场中，我们建立了有效竞争均衡的存在以验证经济可行性，这意味着自私的市场参与者可以以分布式方式获得最大的社会福利。
