目前的电网使用两种属性来分配电能：永久通电和可自由获取电量。这两个属性虽然实用实用，但也使电网面临超载和用电量预测的不确定性。此外，电力分配可能很难管理；突然的需求激增或供应短缺可能最终导致故障。为了克服这一点，我们采用了最近提出的一种方法，即通过这里所称的控制输送电网，以离散的数量输送电力。在这种电网中，用户的地址嵌入在电信号中，智能负载被用来限制供应的电力。这些智能负载不仅可以控制电能消耗，还可以为配电回路提供无功稳定。讨论了受控输送电网的体系结构，分析了一种配电管理方案，该方案将配电回路的容量上限设为所需功率的平均值，采用循环调度的送电计划。实验结果表明，在能源紧缺的情况下，配电效率满足了98%以上的用电需求。
The present electrical grid uses two properties for the distribution of electrical power: perpetually energized and with discretionary access to power amounts. These two properties, although functional and practical, expose the grid to overload and consumption forecasting uncertainty. In addition, the distribution of electricity may be difficult to manage; sudden demand surge or supply shortage may ultimately lead to failures. To overcome this, we adopt a recently proposed approach whereby electricity is delivered in discrete amounts, through what is named here as a controlled-delivery power grid. In this grid, the customer's addresses are embedded in the electrical signal, and smart loads are used to limit the supplied electrical power. These smart loads not only control the consumed amount of power but also provide reactive stability to the distribution loop. We discuss an architecture of the controlled-delivery power grid and analyze a management scheme for the distribution of power, where the capacity of the distribution loop is capped to the average of the requested power, adopting a round-robin schedule of power deliverance. We show that the efficiency of power distribution satisfies over 98% of the power requests in such scenarios of energy scarcity.
