Project Summary

A microgrid is a smart energy grid that combines different energy storage devices to produce electricity for smart appliances and smart meters. In rural areas, grid energy is not fully available, but these areas have the potential to produce and serve electricity from renewable sources.

One of the major problems that obstruct the development of standalone microgrids is the poor life of the storage batteries and the unreliability of renewable sources. To solve this issue, hybrid energy systems (HES) and novel power management strategies have been to enhance the service life of battery banks and increase the reliability of renewable PV-WIND Hybrid systems.
 

 

Project Objectives

The developed model is useful for energizing remote rural areas and produces a system  with  high reliability,

Also, we will cover the drawbacks that cause by these sources like harmonics, reliability, and increase the battery life by using the different algorithm in different climates conditions to make the system more effective.

The main objectives here in the project is to design and develop such a system that will overcome the instability, unreliability on the input side and increase the battery life by using multiple batteries having different properties from one another (lead-acid, li-ion, Ni-Cd Ni-MH) and supercapacitor for high energy density which normally lack by the batteries. 

Project Implementation Method

PV-wind hybrid energy system’s main components are s. PV array and wind turbine generate energy for the load. Battery stores excess energy and supplies the load when the generated energy is not enough for the load. Battery charge controllers keep battery voltage within a specific voltage window and thus, they prevent over-discharge or overcharge regimes. To protect the battery against overcharging, the PV array and wind generator are disconnected from the system when the DC bus voltage increases above and when the current required by the load is less than the current generated by the PV array and wind generator. They have connected again when DC bus voltage decreases below. To protect the battery against excessive discharging, the load is disconnected when the DC bus voltage falls below and when the current required by the load is greater than the current generated by the PV array and wind generator. The load is switched on when DC bus voltage increases above. The inverter converts generated energy from DC to AC for an AC load.

Also, different batteries are used for different purposes in case of low-frequency lead-acid battery will be used as the primary source for medium frequency li-ion and Nickel Cadmium is used as a secondary source and supercapacitor is used for high frequency and instant load change to protect batteries from damage.

Currently, we are working on the modeling of batteries and solar in the Matlab Simulink software and observe the performance of every component individually.

 

Benefits of the Project

The pv -wind microgrid with energy storage device system as an attractive solution for off-gid communities and Allows you to store excess solar or low cost (off-peak) electricity. Most hybrid inverters have backup power capability.

The main benefit is that it will give us full time access to energy in any climate (sunny cloudy and rainy) and reduce up to 25% the consumption of conventional energy sources like diesel fossil fuel and also overcome the technicaland financial viability of the system.

The proposed system will improve life expactancy of the battery and reduce the operating cost, harmonics and increse the reliabilty .

Another benefit is system reliable, sustainability and other factor will be observe under (MPPT, P&O etc).

Also increase the capability of the system when hybrid system is used.

Technical Details of Final Deliverable

As discussiesed earlier to inter connected different energy sources and multiple battery having different chemistry it is important to find the individual behavior of individual compoent in the system to minimize the complexity for the design engineer and easily understandable for the researcher in future who work on this project.

==> Hybrid energy resources is used to overcome climate change factor.

==> Storage batteries is used to overcome load demand and store access amount of energy.

==>. Supercapacitor is used to overcome battery stess during suddent load exchange.
