我们提出了两个试验台和实验评估的控制输送功率（CDP）网格。在CDP电网中，能量是可寻址的，并且功率量是真实的分配给用户的。能量供应商赠款供应给用户的能量的量，并且同时确保总供应能量在固定上限内。能源数量被离散化，以最大限度地减少管理复杂性，并针对数字控制进行优化。我们的一个测试平台模仿了当前的电网，另一个模拟了配备了储能的电网。在所提出的实验中，用户请求并通过低成本计算机实现的电力接入点接收赠款。供应商的管理和控制平面由工作站实现，用户和供应商通过数据网络进行通信。服务器控制120伏交流电源线，并向接入点供电。供应商能够在有限的产能条件下，在满足请求和提供能源方面保持较高的满意率。
We present two testbeds and experimental evaluations of the controlled-delivery power (CDP) grid. In the CDP grid, energy is addressable and the amount of power is allocated to users in real time. The energy supplier grants the amount of energy supplied to a user and at the same time, ensures that the total supplied energy is within a fixed cap. Energy amounts are discretized to minimize management complexity and optimized for digital control. One of our testbeds mimics the present grid and the other emulates a grid provisioned with energy storage. In the presented experiments, users request and receive grants through power access points implemented with low-cost computers. The management and control plane of a supplier was implemented with a workstation, and users and supplier communicated through a data network. Alternating current (AC) at 120 V power lines were controlled by the server and delivered power to the access points. The supplier was able to maintain a high satisfaction ratio in terms of requests granted and energy delivered under limited capacity conditions.
