22. Why Solar-Wind Hybrid
power generation system

23. Photovoltaic array is not available on night hours &
rainy seasons.
On the other hand, the wind speed also varies.
Efficiency & performance of the Solar-Wind hybrid
system is better than the single system of
Solar panel & Wind turbine.

25. 17/05/2020

26. Maximum power point tracking (MPPT) is a technique used
commonly with wind turbines and photovoltaic (PV) solar systems for
maximizing the power under all conditions.
Wind turbines & PV solar systems exist in many different configurations
with regard to their relationship to inverter systems, external grids,
battery banks, or other electrical loads
17/05/2020

27. 17/05/2020

28.  The purpose of the MPPT system is to sample the output of
the Wind turbine & PV cells and apply the proper resistance
(load) to obtain maximum power for any given
environmental conditions
17/05/2020

29.  As the amount of sunlight & the speed of air varies, the load characteristic
gives the changes in efficiency for power transfer.
 The efficiency of the system is optimized when the load characteristic
changes to keep the power transfer at highest efficiency.
 This load characteristic is called the Maximum Power Point (MPP) and
MPPT is the process of finding the point.

31. Strategies for operation of an MPPT
17/05/2020

32. By monitoring the static impedances
 A small signal current is periodically injected into the array bus as well as
static bus impedances (Zd and Zs respectively) are measured. The
operating voltage is then adjusted until the condition Zd = - Zs is achieved.
17/05/2020

33. By monitoring the output power
 The value of dP / dV is zero at maximum power point. This property is
utilized to track the minimum power point. Voltage is adjusted and power
output is sensed. The operating voltage is increased as long as dP / dV is
positive. That is, voltage is increased as long as we get increased output.
 If dP / dV is sensed negative, the operating voltage is decreased.

Maximum Power Point Tracking in
Solar-Wind Hybrid system
for Battery Storage Application
In this paper, authors designed a hybrid
power generation model to produce
electrical power from renewable energy
(using windmill & solar). They designed the
project including solar panel, dynamo,
rectifier & battery. But they didn’t use any
tracking or controlling system to increase
the efficiency.
We also designed a model of hybrid system
using renewable sources. It’s very useful as
an alternative power generation system of
non-renewable sources. We used an MPPT
technique in this system to get maximum
power. By using this technique efficiency
can be increased.
