Abstract
A method of controlling assets connected to an electricity distribution grid operating at a predetermined grid frequency is disclosed. The assets comprise assets supplying electrical energy to and/or consuming electrical energy from the grid, with at least some of the assets being configurable to adjust energy flow to or from the grid to counteract grid frequency fluctuations. The method includes configuring an aggregate response by a group of assets to fluctuations in the grid frequency, wherein the aggregate response comprises respective adjustments of energy flow between each of the group of assets and the grid. The adjustments are arranged in combination to counteract a fluctuation in grid frequency. A divergence is detected between a first grid frequency measured in a portion of the grid comprising a first asset of the group of assets and a second grid frequency measured in a portion of the grid comprising a second asset of the group of assets. In response to detecting the divergence, at least one of the first and second assets is reconfigured to alter the energy flow adjustment for that asset. Reconfiguration may involve clustering assets based on grid frequency and reconfigu…
