A platform-based approach to distribution operations

The energy landscape today is undergoing significant transformation as distribution network operators (DNOs) continue making the transition towards distribution system operators (DSOs). Led by widespread growth of distributed generation – including 27.0GW of installed rooftop solar capacity globally in 2017(1) – along with battery storage, electric vehicles (EVs), and other forms of distributed energy resources (DERs), DSOs face significant changes to the traditional energy delivery model. Coupled with an evolving regulatory framework, in order to continue to provide safe, reliable, and affordable grid services, DSOs are looking at new, modern approaches to safely connect, model, manage and optimise customer DERs within the overall network.

A whole new world

Whether you agree with its conclusions or not, the Cost of Energy Review lays out a clear, and at times sobering, review of the development of the electricity sector over the last 50 years and its present complicated structure. For those of us who have been arguing that we need radical change it certainly offers that. It covers all aspects of electricity supply but I’m going to look at the proposals for networks which are probably more far reaching than for other areas, even if they have received less attention.

ABB and Rolls-Royce announce global microgrids cooperation

A microgrid is a small scale electric grid that combines power from distributed energy generation sources such as combined heat and power plants, diesel- and gas-powered gensets and renewable sources with batteries. The microgrid provides the overall control to coordinate these resources to meet the requirements of industrial, residential or consumer loads. Microgrids can either function off-grid, or connected to the main power grid. The ability of microgrids to seamlessly separate themselves from the main grid, in the event of a potential grid fault or emergency, is an increasingly important feature.
