Abstract

Photovoltaic (PV) hybrid systems and their optimal energy management are still being actively studied. PV systems must be positioned at optimal tilt and azimuth angles to obtain maximum system performance. This article presents the effect of energy management of a grid-connected PV-battery-load system on optimal PV placement using a Linear Programming (LP) method. The optimal placement of PV arrays aims to minimize the electricity cost of a fixed PV system for investors by considering monthly average daily global radiation, ambient temperature, wind speed, demand management constraints and electricity tariffs in Turkey. The analysis is extended to consider 68 locations across Turkey. The analysis reveals that optimal placement (optimal tilt and azimuth angle) can be different from that of previous studies because of multiple objective considerations. The optimal tilt angle results are lower than the local latitude in the range of 0° to 8° in all regions. Furthermore, the optimal azimuth angle results are in the range of 6° to 24° westbound throughout Turkey. These results can play a significant role for investments in the design of grid-connected PV-battery-load systems.
