Smart meters have grabbed a lot of the limelight when it comes to the smart grid. But, let’s face it, next-generation intelligence in substations is the fulcrum for bringing more renewable energy into the electrical distribution network. Smart meters delivered intelligence to the grid’s end points, but increasing intelligence in substations via smarter intelligent electronic devices (IEDs) will enable regional supervisory control and data acquisition (SCADA) systems to more effectively manage power supply and demand in grid segments that contain renewable energy sources...
