Abstract

This work aims to determine the optimal hybrid of an autonomous
generation system of renewable energy sources (RESS) to supply an
isolated load. This system includes solar photovoltaic generators, wind-
generators and energy storage units. A technical and economical model is
introduced here to optimize the combined energy of this hybrid system.
This model depends on the hourly solar radiation, wind speed and the
load demand at the considered site, in addition to the economical
parameters and operational constraints of the aforementioned RESs.
The suggested model is applied numerically with the nonlinear
programming for planning photovoltaic and wind energy systems to
supply an isolated load in remote area of Egypt. Also, the capacity of
energy storage units to ensure the continuity of the power supply used is
determined and optimized by a load management technique. The
combined energy of this hybrid system is optimized from economical
point of view.
