Micro grid smart grid and utility
The biggest energy challenge of the 21st century is to supply electrical energy to the consumer with the least possible cost while maintaining a high quality of continuous power supply. For Continuous Supply extra burden has to be put on generation stations, while cost of electricity keeps on rising due to poor transmission capabilities.
Future of power systems highly rely on renewable energy sources. Low cost pollution free solar energy has opened new dimensions for the generation of power to support the existing grid system. The general trends in the past decade of increasing solar cell efficiency, decreasing PV system costs, increasing government incentive programs, and several other factors have all combined synergistically to reduce the barriers of entry for PV systems to enter the market and expand their contribution to the global energy portfolio. Economic is mean by which the energy is produced at the lowest cost to reliably serve the consumers while considering operational limits of generations and transmission. The aim of this project is to design a model of Micro grid, Smart grid Power System with multiple sources synchronized with the grid The end product will be a compact device reducing burden on generating stations
In our project, we are working to develop a model of a Micro grid Smart gridPower System and this will support the existing grid system by suppling excess power to the grid and to nearby loads and also will reduce the unit cost of electricity. This project can in future be used in the Power Engineering Lab at HAMDARD to demonstrate the behaviour of PV panels, Grid tie inverters, Controllers and Hybrid systems. Also, using this device and algorithm, concepts of how to manipulate power can be taught and strategies to obtain the lowest unit cost can be made.
THE IMPLEMENTATION IS DIVIDED INTO DIFFERENT TASKS BREAKUP.
Task1: - Research
Task2:- Learning Design & Literature Review
Task3:- Cost Analyzing
Task4:- First Evaluation Presentation
Task5:- Study Control Algorithm
Task6:- Hardware Implementation
Task7:- Testing
Task8:- Assembling And Peaking
It will reduce the unit cost of consumer.
It will provide continuous power supply to the consumer
It will support the existing grid system by feeding extra power back to the grid
It uses a smart algorithm to decide the best source for drawing power from multiple options.
It’ll be an indigenously developed, economical and efficient solution for consumers and industries.
SOLAR PHOTOVOLTAIC MODULE.
A photovoltaic system converts light into electrical direct current (DC) by taking advantage of the photoelectric effect. A solar panel is a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A photovoltaic module is a packaged, connected assembly of solar cells.
MPPT CHARGE CONTROLLER.
Maximum power point tracking is a technique that grid connected inverters, solar battery chargers and similar devices use to get the maximum possible power from one or more photovoltaic devices, typically solar panels.
DC DC BOOST CONVERTER.
Dc boost converter is used to increase the voltages to a
required level
H – BRIDGE GRID TIE INVERTER.
A conventional inverter can be divided into two parts, one is the power circuit part and the other is the control circuit part. The power circuit is normally built up from MOSFET or IGBT switches.
UTILITY GRID.
A utility grid is usually a commercial electric power distribution system that takes electricity from a generator (e.g., fossil fuel boiler and generator, diesel generator, wind turbines, water turbine, etc.), transmits it over a certain distance, then takes the electricity down to the consumer through a distribution system. The entire system is referred to as the grid.
