Abstract
This work investigates the hypothesis: “grid-connected batteries will not export energy at times of high wind energy availability in Scotland, nor add to network congestion.” The likely rational behaviour of a short-duration (two-hour) battery, engaged in trades in the wholesale electricity market in Great Britain is simulated, for three case study periods during 2022, using scenarios of different trading strategies and foresight of market price. In the scenarios yielding highest revenues, times of battery import and export actions are compared with times of Scottish wind energy availability and transmission network congestion. Results show such a battery will continue to trade, both importing and exporting, during periods of high wind availability, conditions under which network congestion is common. Thus, the possibility that short-duration batteries may add to network congestion by exporting during periods of high wind availability must be allowed for by network planners, the system operator and the regulator. Market, network and / or regulatory solutions are needed.
