| Summary: | Fluctuation of wind energy and solar radiation that is inconsistent become a major challenge
to build alternative power generation. The uncertainties to two energy sources is a problem in
synchronizing. To build a plant, first performed testing the potential energy that can be
harnessed. Testing the potential of wind energy using Weibull distribution methods and
estimation of solar energy radiation using a model Annandale, Hargreaves and the proposed
model as well as to these three models were tested statistically using MATLAB simulation.
Wind energy and solar radiation are fluctuating and inconsistent results in the voltage
generated are not constant. For the voltage is not constant can be fixed using a buck-boost
converter. Buck-boost converter is a dc-dc converter that can increasing and decreasing the
voltage. Design buck-boost converter uses a combination of electronic components such as
inductors, capacitors, diodes, XL6009, TIP2955 and LM7815. Of a difficulty to combine the
two plants directly with a voltage are not constant. Merger of wind energy and solar radiation
using a microcontroller, which serves to connect or disconnect the two energy sources to the
electrical power system, if one or two sources of energy have a voltage less than or greater
than the voltage is specified, then the microcontroller works to break source energy to the
battery. If one or both energy sources have the same voltage with the voltage specified, then
the microcontroller to work connecting the energy source to the battery. Based on MATLAB
simulation that the potential for wind energy and solar radiation in Perlis show that wind
energy is low at maximum wind speed of 1.10 m/s in PDF 0.44 (in 2011) and a maximum
wind speed of 1.11 m/s in PDF 0.51 (2014), while the results of estimation and statistical
tests (CRM, RMSE and e%) for solar radiation using MATLAB shows that the proposed
model (combination Hargreaves and Annandale model) is better than model Hargreaves and
Annandale and energy of solar radiation is very good with solar radiation average 1,316
wh/m2 (above the standard value of 1,000 wh/m2). Design and development of buck-boost
converter with the addition of components Inductors 35.5 μH and capacitors 220 μF can
increasing and decreasing the voltage of the source of wind energy and solar radiation.
Implementation buck-boost converter in the synchronization system wind energy (WP) and
photovoltaic (PV) is used for charging batteries. The battery charging of 5-6 hours and
discharging the battery of 28 hours. |
