Digital Control System for Solar Power plant

using IoT
Ganesh V. Karbhari, Pragya Nema


Abstract: The Internet of Things (IoT) or Web of Things (WoT)
is a modern technology which is relating computing machines
with digital and mechanical devices and various objects. Today
energy crisis is one of the major issues in the world. To overcome
this issue, different renewable energy sources are being used.
Nowadays solar energy has become a best alternative resource for
satisfying power demands. Selected Solar power plant for
implementation is of 1 MW capacity and generating power of 1.5
Million units per year with the use of Poly crystalline type of solar
panel technology. Currently this power plant is monitored by PLC.
All records of energy can be monitored only at plant on SCADA
Device. In this Proposed work, we develop a model of online solar
power monitoring as well as controlling so authorized person can
monitor or control panels remotely by home also. As per the
change in the atmospheric or weather conditions, user can control
the solar panels also.

Index Terms: IoT (Internet of Things), Solar energy, SCADA, Fig.1. Internet of Things (IoT)
PLC etc.
Fig. 1 explains the functioning of IoT. IoT will make a
tremendous impact in the retail industry.

started various procedures in it, also in paper [12] suggested
about such integrated system. Main Key features of these
systems [12] are that they combine the remote monitoring
functions and the management into the one system so it has
modified user interfaces. Within wind turbines and solar
panels, implementation of real time solar power monitoring
infrastructure is also discussed [10].
