STUDY ON OPTIMAL INSTALLED CAPACITY OF PHOTOVOLTAIC AND BATTERY TO MINIMALIZE TOTAL COST IN FACTORY

摘要

In this paper, a method of scheduling scheme for the electric supply of Factory Energy Management System (FEMS) is presented. Additionally, optimal installed capacity of photovoltaic (PV) cells and battery to minimalize total cost is calculated. PV output including uncertainty is forecasted by using Just-In-Time Modeling (JIT Modeling), and scheme for the electric supply is scheduled based on the forecasted data. Furthermore, simulation for scheduling scheme is carried out with proposed method in various capacity of PV cells and battery, and optimal capacity to minimalize total cost including each initial cost is calculated.
