Energy Management System for optimization of cost and dis-connectivity of load
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryThe increasing electricity cost and everyday disconnectivity of our local grid power stations is the biggest problem in our country. So our team has come with a well-thought-out solution to control the unmanageable energy crisis.
In this regard our team is looking to implement state of the art ENERGY MANAGEMENT SYSTEM (EMS) that uses PV arrays powered by battery banks optimizing a micro-grid connection with the main grid.
Working Principle:
It will be able to manage a 100W variable load 3-source connection during its first phase of development.
1. Main Grid.
2. Solar System (PV).
3. Battery Bank.
Controlling phenomenon:
We design an energy management system for maneuvering these three power sources. Our controlling system incorporates micro-controller, voltage sensors, and Real-time Clock (RTC). These three power sources are switched through three relays that control the system in accordance to programming conditions.
These are the following conditions for switching:
1. Our first priority of power source collection for the load in day time is solar energy system.
2. If the solar energy isn’t available due to cloudy weather, dust storms, or rainfall, we switch towards the main grid.
3. During load-shedding peak hours we switch towards battery bank for the continuous power supply to the load.
4. For the remaining time period, we switch to the main grid.
The schematic diagram of our project is given below.
The main objective is to design a prototype of an Energy management system that minimizes the energy cost and provides uninterrupted electricity supply meeting the load demand.
According to the impact of energy, energy saving is very essential in reducing the costs of the energy.
Due to surplus energy consumption, energy saving has become an essential phase to reduce overpriced energy costs.
Project Implementation MethodProteus Professional Software is probably the solution for real-time application simulation; it is proposed for accurate EMS micro-grid operations.
An optimal energy management algorithm is being developed for PV/battery stand-alone system. These statistical values are capable to manage and organize different modes of operation. The modeling of PV cell will be analyzed with the MPPT technique. Battery will be connected via bi-directional DC-AC converter to compensate the AC load. The DC-inverter seems to be the answer to this specific process.
Benefits of the Project- Reduce Electricity Cost:
The most possible advantage of this energy management system is that it will save ample electricity cost. This reliable management system will save plentiful voltage energy, resulting in lesser-to-non voltage crisis.
2. Reduce Load-shedding:
The automated energy-switch triangle consisting of the main grid, solar panel, and battery will reduce load-shedding to a great extent.
3. Main Grid Energy Saving:
Solar Energy and Battery Storage during electricity consumption at peak hours of daylight will save abundant grid energy.
4. Auto Switching:
The EMS (Energy Management System) will deliver on-time scheduling. The employment of voltage sensors and RTC Clock modules will enable accurate astronomical calculations to predict exact times of sunset and sunrise. Thus, the lights will turn on and off without any human intervention i.e., automatically. It can also be set manually.
Its installation and management would be done through programming.
5. Environment friendly.
6. Green Technology.
Technical Details of Final DeliverableThe project at completion shall be expected to do following output:
Energy Management System will optimize the cost of micro-grid, in return, supply uninterrupted power to load. Therefore, providing with ample electricity to the masses, the menace of load-shedding will be over.
EMS has become a potential state-of-the-art system for micro-grids. It will provide many-sided source selections as per their availability. Its voltage source will work on the energy source first-hand accessibility system i.e., it will utilize the ideal energy suited for the time being. Therefore, it will meet the load demand effectively.
This criterion will help decrease the load-shedding and high amounts of costs in micro grid. Consequently, there’s been an intuitive increase in the systems overall efficiency.
The proposed EMS for micro grid has been designed in order to follow the charging and discharging characteristics of the battery bank (BB). It ensures a long-lasting battery life performance.
