Pika energy9/4/2023 ![]() With Amber’s recently announced devices, the Amber AC/DC Enabler™ and Amber AC Switch™, solid-state digital control of electricity is now possible in every device, appliance, power cord endpoint. One example is Amber Solutions, a startup focused on the development of a hyper-intelligent electrical architecture. The emergence of nano grids is attracting startups with new solutions. A nano grid supports the integration of renewable power sources, smart loads, and storage in homes and small buildings (Image: Laurence Berkeley National Lab) Nano grids are designed to optimize these tradeoffs. AC power from the local utility is more reliable but has a higher, and often variable, cost. ![]() Solar panels may have very low marginal costs of electricity, but they are generally intermittent. Each source has different tradeoffs between availability and costs. As a result of these trends, buildings can have multiple power sources, both AC and DC. The increasing installation of solar and storage in homes and other buildings drives the growth of nano grids. Nano grids and zero net energy consumption One of the ultimate goals of both nano grids and microgrids is to support zero net energy consumption and corresponding greenhouse gas reductions. A nano grid, on the other hand, is typically no larger than a single house. Microgrids range in size from large commercial and industrial buildings to military bases or college campuses. Microgrids consist of groups of connected power sources and loads. In some areas, that challenge is being met using microgrids and nano grids. One of the architectural changes occurring in the electric grid is to accept a less reliable primary grid and push the maintenance of quality, sustainability, and reliability to the edge. Matching supply and demand for electricity is a growing challenge. Smart grid, the software-defined grid, and big data will be the focus of the third FAQ. ![]() Part two will look at the growing use of virtual power plants and distributed energy resources. It begins with the emergence of nano grids, microgrids, and the possibility of increasing the grid’s flexibility. This FAQ series will look into some of the changes taking place in the electric utility grid architecture. And the use of traditional centralized power generation does not meet society’s environmental expectations for clean and green energy. Aging transmission and distribution systems are significantly reducing both the quality and reliability of electricity. The centralized grid that was designed to provide inexpensive electricity with a reasonable level of quality and reliability is no longer meeting society’s needs. Electric utility grids around the world are undergoing a fundamental change in architecture.
