Abstract
Advanced energy storage systems have been widely applied to industries and are being installed at large buildings and factories to realize efficient energy usage. This paper presents a control method of load frequency control and distribution network control (loss reduction control) using a part of customers' owned battery capacity. When 10% of total battery capacity of 100MW in the network of 30GW generator capacities is used for load frequency control, a total of 1500MW generation units for load frequency control, at maximum, can be stopped without deterioration of power quality. In addition, when batteries are used for loss reduction of distribution network, 2% of loss on a summer day can be reduced. To realize both effects in maximum, the novel integrated control algorithm is proposed and its economical effect is evaluated by numerical simulations.
