Realisation of a cloud based Data Acquisition System (DAS) for grid connected solarised homes

Grid connected solarised homes are becoming very popular in the recent times and Government of India (GoI) is giving emphasis to increase the photo-voltaic (PV) generation in order to reduce the dependency on the conventional energy sources. But due to the unpredictable nature of the solar PV generation connected to the distribution system, forecasting of load becoming difficult for the local utilities. Energy management systems (EMS) can be very useful for such grid-connected solarised homes so as to utilize green energy consumption locally when the utility power balance is already maintained. Such a system can also be useful to reduce the energy requirements throughout the day and thereby having monetary benefits as well. In order to realize such an EMS, development of a suitable DAS is a must. An attempt is made in this paper to realize a cloud based DAS for acquiring data from different sensors and store the information in the cloud based on which switching of different relays can be performed. The work will be extended further to develop the utility assisting EMS suitable for grid-connected solarised homes. Furthermore, there are several future scopes of this work in different applications.
