Microgrids aren’t a new idea. In industry parlance, a microgrid is a small network of electricity users with access to a local source of energy. The users are all directly connected to the central grid, but during outages, the entire small network can disconnect itself from the central grid, or operate in “island mode,” to. . In traditional energy-supply systems, control and optimization of power is coordinated among a relatively small number of centralized resources. Control servers optimize the generation, output, and flow of energy from. . Another advantage to autonomous control of small-scale, on-site power generation is that it’s a step toward a long-desired wish of many renewables. . Ultimately, von Meier said she sees the grid of the future necessarily evolving into a complex hybrid of old and new. Local power generation will be just as important as the distribution of. . One problem, Bernstein noted, is the current lack of standards for how DERs connect to the grid. So creating control software for them is particularly tricky. “You can develop a very. [pdf]
