Bidirectional Sharing of Distributed Generation with Traditional Grid
Project Area of Specialization Artificial IntelligenceProject Summary-
Net Metering is a billing mechanism that credits solar energy system owners for the electricity they add to grid. If our distributed generation system generates excess energy it will add to the grid and whenever it doesn't generate enough energy to meet our needs then the energy is taken from the Grid.
-
Basically, it's a two-way communication process.
-
Current transformers and potential transformer are used to sense current and voltage generated by our PV module and Grid.
-
two Arduino UNOs are used to control and calculate energy flow from both sides.
-
two 16*2 LCDs are used to display the Current, Voltage, Power and Energy consumed by the load.
-
Relays are used in this project for switching purpose.
- To reduce electric demand pressure from the grid.
-
To reduce electric disruption risk.
-
To achieve autonomy of utilizing the energy all the time.
-
To encourage customers to move towards renewable energy.
-
To preserve natural energy resources.
-
Preventing the need for new power plants that would produce pollution.
-
To make a smart net metering system.
Our project has three parts. First one is our Distributed Generation system, second is the main supply(Grid) and the third one is the load connected to both Distributed Generation system and Grid.
electronic components are installed on PCB. We use the inverter to convert DC supply Of the PV module into AC. A current transformer and potential transformer are used to sense the current and voltage and information is sent to the Arduino UNO. A 16*2 LCD is connected with the Arduino to display the energy consumed by the load. The same process is done with the second part as energy from the Grid is sensed by CT and PT.
The Arduino UNO is used to take a reading from CT, PT and show output on the LCD connected to it. We give priority to our Distributed Generation system to run Appliances. We use Relays for switching purpose.
For example, if we want to turn ON three bulbs and the DG system is generating energy for just two bulbs then the third bulb will be switched to Grid.
Benefits of the Project- The most obvious benefit of net metering is to consumers. If you install net metering in your home, you can reduce the amount of money you spend each year on electrical energy. You can even make money if you produce more than you consume and your utility company pays you for that excess energy at the retail price.
- The system is easy and inexpensive. It enables people to get real value for the energy they produce, without having to install a second meter or an expensive battery storage system.
- It allows homeowners and businesses to produce energy, which takes some of the pressure off the grid, especially during periods of peak consumption.
- Each home can potentially power two or three other homes. If enough homes in a neighbourhood use renewable energy and net metering, the neighbourhood could potentially become self-reliant.
- It encourages consumers to play an active role in alternative energy production, which protects the environment and helps preserve natural energy resources.
- Homes that use net metering tend to be more aware of, and therefore more conscientious about their energy consumption.
- It saves utility companies money on meter installation, reading and billing costs.
- The old concept of this project is not so efficient than our proposed project. This is because when the Grid supply is off then the DG system will off automatically because of Islanding but we introduce an idea in which when Grid supply is off, our DG system will continuously generate energy.
It will be a hardware-based project as all components are installed on PCB.
PCB will be designed for the components like CTs, PTs, Mosfets, resistances, capacitors and diodes. Load and relays are not part of the PCB.
There will be three parts:
1-Distributed Generation system
2-Main supply(Grid)
3- load
the load is connected with both the DG system and Grid by using Relay Box for switching purpose.
