1. A method of controlling assets connected to an electricity distribution grid operating at a predetermined grid frequency, the assets comprising assets arranged to supply electrical energy to and/or consume electrical energy from the electricity distribution grid, wherein at least some of the assets are configurable to adjust energy flow to or from the electricity distribution grid to counteract grid frequency fluctuations, the method comprising:
configuring an aggregate response by a group of assets to fluctuations in grid frequency, wherein the aggregate response comprises respective adjustments of energy flow between each of the group of assets and the electricity distribution grid, the adjustments arranged in combination to counteract the fluctuations in the grid frequency;
detecting a divergence between:
a first grid frequency measured in a portion of the electricity distribution grid comprising a first asset of the group of assets; and
a second grid frequency measured in a portion of the electricity distribution grid comprising a second asset of the group of assets; and
in response to detecting the divergence, reconfiguring at least one of the first and second assets to cease, or modify a magnitude of the configured energy flow adjustment for that asset to alleviate, or avoid exacerbating the divergence between the first grid frequency and the second grid frequency.
