Accelerating innovation

Substation monitoring has been an area of interest amongst distribution network operators (DNOs) for some time, as the way consumers use and interact with the network changes due to the relatively rapid growth of photovoltaic installations, electric vehicles, domestic-level battery storage and so on. Before these relatively new technologies were widely adopted, it was sufficient to manually record a reading from an analogue maximum demand indicator during a physical inspection once or twice a year, but this is no longer considered sufficient by many in the industry who are now interested in annual and diurnal patterns, harmonics and more.

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.

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.
