The "SmartGrid" is a concept that has emerged from its initial discussion in engineering circles into the wider public arena because its importance has been recognised for securing future electricity supply and facilitating the de-carbonisation of electricity. Much of the SmartGrid debate has so far focused customers with "smart homes" or "smart appliances" being engaged in managing the electricity system through their reactions to signals about price or availability of renewable energy. Behind the scenes, there is a parallel debate about how new control methods for existing electricity plant and equipment may enable electricity networks to offer the flexibility needed to incorporate low-carbon energy sources. This proposal expands the SmartGrid debate in two directions. First, large numbers of people in developing countries suffer from an intermittent electricity supply. The supply companies use "rota disconnection" schemes to ration the limited energy available in some regions. Having electricity for, say, just 4 hours a day adversely impacts education, health care and economic development. "Micro-grids" able to run "off-gird" with local solar or micro-hydro energy are interesting in this context. Our proposal here is to design "on-off grids" in which supply companies adjust their rota disconnection to account for local resources in the micro-grids and the micro-grids are configured with power electronic interfaces that can manage the frequent transitions between on-grid and off-gird operation. The consortium members in India will build a demonstration version of such a micro-grid to allow control and optimisation ideas to be explored and assessed. The use of energy storage technology will be a key part of this scheme.Second, developed countries do not suffer rota-disconnections except in emergencies. However, the security and adequacy of their existing electricity distribution networks may become compromised by the injection of significant amounts of solar energy at household level and the heavy loading anticipated from electric vehicle charging. Here we propose to develop power electronic equipment that enables the rapid reconfiguration of the possible supply routes in a network in order to optimise the power flows and voltage levels. The questions are not so much on can power electronic devices achieve this (we are confident they can) but rather how is it achieved efficiently and with a good equipment lifetime. The UK members of the consortium will design, build and test new forms of "soft meshing" power electronics to meet these objectives.The "reconfigurable distribution network" presents a great opportunity in both the Indian and UK context. It also present research challenges on a number of fronts: innovation in power electronic equipment to reduce power losses and increase lifetime; the need to design new control algorithms to exploit the new flexible equipment to the benefit of consumers and network operators and the need to create new optimisation and planning tools to indicate where exactly the new equipment should be deployed and to determine how robust its business case can be.

“智能电网”是一个概念，从最初的工程界讨论发展到更广泛的公共领域，因为它在确保未来电力供应和促进电力脱碳方面的重要性已得到认可。到目前为止，关于智能电网的争论主要集中在拥有“智能家居”或“智能家电”的客户身上，这些客户通过对价格或可再生能源可用性信号的反应来管理电力系统。在这背后，还有一场平行的争论，即现有发电厂和设备的新控制方法如何使电网提供纳入低碳能源所需的灵活性。这一提议将智能电网的争论扩展到了两个方向。首先，发展中国家的大量人口遭受间歇性电力供应的困扰。供电公司使用“轮流断网”计划，对某些地区有限的可用能源进行定量配给。比如，每天只有4小时的电力供应会对教育、医疗保健和经济发展产生不利影响。在这种情况下，能够利用当地太阳能或微型水力能源“离网”运行的“微电网”很有趣。我们的建议是设计“开关电网”，其中供电公司根据微电网中的本地资源调整其轮转断开，微电网配置电力电子接口，可以管理并网和离网运行之间的频繁转换。印度的联盟成员将建立这样一个微电网的示范版本，以便探索和评估控制和优化的想法。储能技术的使用将是该方案的关键部分。其次，发达国家除了在紧急情况下，不会遭遇轮转中断。然而，由于大量太阳能在家庭层面的注入以及电动汽车充电预计带来的沉重负荷，现有配电网络的安全性和充分性可能会受到损害。在这里，我们建议开发电力电子设备，使网络中可能的供电路线能够快速重新配置，以优化功率流和电压水平。问题不在于电力电子设备能否实现这一点（我们相信他们可以），而是如何有效地实现这一点，并具有良好的设备寿命。该联盟的英国成员将设计、建造和测试新形式的“软啮合”电力电子设备，以实现这些目标。“可重构分销网络”在印度和英国都是一个巨大的机遇。它还提出了许多前沿的研究挑战：电力电子设备的创新，以减少功率损耗和延长寿命；需要设计新的控制算法来利用新的灵活设备，为消费者和网络运营商带来利益，需要创建新的优化和规划工具，以确定新设备的确切部署位置，并确定其商业案例的稳健程度。
