Smart Solar Hybrid Inverter in Grid Oriented System for Utilizing PV Energy
Project Area of Specialization RoboticsProject SummaryWe want to design and implement a Smart Hybrid Inverter, this prototype has continuous power supply to ensure continuous output current to load in commercial applications by utilizing both Photovoltaic (PV) energy and AC Grid. This proposed intelligent designed inverter during peak hours hybrid inverter give priority to PV solar power and it gives power to the commercial appliances and charge the batteries, when the PV cell give maximum Power. On the other hand during cloudy weather it shift the commercial load to the Grid while in night time it operate commercial load on Grid system and when the Grid is off it supplies power from batteries. Solar energy gets priority here to charge storage battery rather than AC source that may save hundreds of megawatts power every day. To increase the battery life spain and keep system components hazard-free, it includes exact battery-level sensing, charging-current controlling by microcontroller unit (MCU) and a cumulative DC/AC MPPT (Maximum Power Point Tracking) charging to congregate- collect maximum PV energy from AC Solar Modules.
Project Objectives1. Continuous supply of power during hours of unplanned load shedding at domestic level.
2. Utilizing maximum solar energy to reduce expensive utility tariff.
3. Rescheduling maximum power-consuming tasks during hours of maximum PV generation.
4. Smartly managing battery storage by shifting load back to utility in order to minimize battery discharge.
The implementation of this Proposed FYP contains following sections:
a) Switching Circuitry contains Monitoring, Control and Management of Electric Loads in Domotic Environments.
b) Implementation of Maximum Power Point Tracking (MPPT).
c) Battery charging including Battery charge controlling, Exact level sensing,Overcharge and Overload Protection.
d) DC/AC conversion through inverter.
Benefits of the ProjectProblem Statement/Motivation:
Large population and comprehensive electrical energy
consumption have made power crisis one of the gravest national problems in the developing countries like Pakistan and many other countries. Excessive demand of power is always difficult to meet and as a result national economy is being hampered severely due to this deregulation of
electricity. To cope-up with this issue the idea of solar energy is proposed. Since generation from solar PV is in DC and most of the appliances at home could be operated on AC.
Solution:
Proposed hybrid IPS (Instant Power Supply) system could be the ideal solution during main grid failure. It has many distinct features over the conventional generators. This precession IPS is designed according to our power line characteristics. Usages of this system ensures, no matter what location or application, safe and reliable generation of electricity to power our equipment’s anywhere the sun shines, even under the most hazardous conditions. Also, this system can provide AC supply with high quality backup in emergency needs during power cuts. These isolated inverter are more likely to get attentions for large applications that demands bulk power. High capacity solar panels and large sized batteries are only needed to provide that support without any moderation of our proposed system.
1. Battery level sensing
