Dispatching of a Scale Nuclear Power Plant using a Battery Storage

In this work, flexible generation is investigated using conventional nuclear generation and a battery storage device. Using unique dispatching, the fixed output power provided by nuclear generation, coupled with the storage device, an equation is formulated to determine the required battery capacity for a single dispatching cycle. A unique averaging constraint will maintain battery charge capacity at the end of a dispatching cycle with the use of a novel algorithm. Both, battery sizing equation and averaging-constraint algorithm are included in a computer model for validation. The level of dispatching or duration can be found, with a given existing system and any battery size, by manipulating the formulated equation. The results show that flexible generation can be achieved using conventional nuclear generation given system parameters and desired rated generation output percentage variations.
