Design and Optimization of Wind-Battery Systems
This chapter gives a detailed account of the sizing and optimization of an isolated wind-battery system. A procedure is proposed which simulates the minimum battery capacity given the resource and load profiles and generator rating-turbine diameter combination along with other system level constraints. Varying the turbine diameter-generator rating combinations enables to generate a set of feasible design options, known as the design space. The design space of a wind-battery system is identified on a rotor diameter vs. rated power diagram. This forms the core philosophy for sizing the system. The optimum configuration of the stand-alone system is identified on the basis of the minimum cost of energy. Similar results can also be obtained by applying principles of pinch analysis originally designed for optimizing heat exchanger networks. Multiple case studies are included to demonstrate the procedure. It is demonstrated that there are maximum and minimum limits associated with each design variable abiding by which it is possible to supply the demand.
