Online control algorithm for sub-half-hourly operation of LV-connected energy storage device owned by DNO

Change in consumer behaviour through uptake of Low Carbon Technologies is likely to put existing distribution networks under strain and worsen the operational requirements of the network. Deployment of energy storage and power electronics is a feasible alternative to traditional network reinforcement. This paper presents two control algorithms used with an energy storage device deployed as part of New Thames Valley Vision Project. The two algorithms are aimed at 1) equalising phase loading with correction of power factor and 2) providing voltage support with Additive Increase Multiplicative Decrease algorithm for active and reactive power control.
