为了支持间歇性太阳能和风力发电的高渗透率，许多地区正在计划增加新的高容量输电线路。这些额外的输电线路加强了电网同步，但也会增加电网的短路能力，而且成本非常高。凭借高度互联的电网和可变的可再生能源发电，小规模的电网故障很容易引发级联停电，导致大规模停电。我们介绍了“数字网格”，其中大型同步网格被分成较小的分段网格，这些网格通过称为数字网格路由器的多分支 IP 寻址交流/直流/交流转换器异步连接。这些路由器相互通信，并通过现有的传输线在分段电网之间发送电力，这些传输线已被重新用作数字电网传输线。数字电网可以接受可再生能源的高渗透率，防止级联停电，容纳可识别的标记电流，记录这些交易，并将电力作为商品进行交易。
To support a high penetration of intermittent solar and wind power generation, many regions are planning to add new high capacity transmission lines. These additional transmission lines strengthen grid synchronization, but will also increase the grid's short circuit capacity, and furthermore will be very costly. With a highly interconnected grid and variable renewable generation, a small grid failure can easily start cascading outages, resulting in large scale blackout. We introduce the “digital grid,” where large synchronous grids are divided into smaller segmented grids which are connected asynchronously, via multileg IP addressed ac/dc/ac converters called digital grid routers. These routers communicate with each other and send power among the segmented grids through existing transmission lines, which have been repurposed as digital grid transmission lines. The digital grid can accept high penetrations of renewable power, prevent cascading outages, accommodate identifiable tagged electricity flows, record those transactions, and trade electricity as a commodity.
