Project Area of Specialization
Project Summary
| Electric vehicles can be used to buffer the irregular production of electricity from future renewable sources, which will contribute to the overall stability of the electrical network. The vehicle-to-grid (V2G) and vehicle-to-house (V2H) concepts aim to optimize the way we transport, use and produce electricity by turning electric cars into ‘virtual power plants’. With this concept, electric cars would store and dispatch electrical energy stored in networked vehicle batteries which together act as one collective battery fleet for ‘peak shaving’ (V2G i.e. Sending power back to the grid when demand is high) and ‘valley filling’ (G2V i.e. Charging at night when power demand is low). Vehicle-grid integration (VGI) describes various approaches to link the electric power system and the transportation system in ways that may benefit both. VGI typically encompasses vehicle-to-grid (V2G) with bidirectional flow of electricity between the vehicle and power grid, in effect treating the EVs as an energy storage device for peak shaving. So, the hybrid based algorithm uses a combination of deterministic and rule based approach for management of PV(Photovoltaic) based EV charging station which reduces the cost of EV charging depending upon specific times (PV as a source during sunny hours and grid as a source during off-peak hours). |

Project Objectives
- The V2G bi-directional method will enable us to perform efficient power management, peak load leveling /valley filling, voltage regulation and effective spinning reserves.
- The project contributes to build a low-carbon society by utilizing renewable energy (PV) and controlling electricity tariff.
- To revolutionize EV market by introducing much efficient, economical and optimized bi-directional energy flow between vehicle and grid.
Project Implementation Method
A photovoltaic (PV)-powered charging station for electric vehicles with power management that integrates vehicle-to-grid (V2G) is based on a DC Microgrid integrating PV sources, the charging station is controlled by a searching peak and valley algorithm (SPVA). The design topology which will be adopted for this prototype will consist of an enhanced bi-directional AC/DC converter powered by PV and public grid. For G2V, the AC from public grid is fed into the DC Microgrid which further processes and charges the EV batteries. For V2G, the DC from EVs is processed through DC Microgrid and fed into public grid if required. Dynamic Searching Peak and Valley Algorithm is adopted to estimate the optimal start operating time of EVs by searching the “peak” periods and “valley” periods of the public grid.
Benefits of the Project
The increase in the number of electric vehicles (EVs) has led to an increase in power demand from the public grid; hence, a photovoltaic based charging station for an electric vehicle (EV) can participate to solve some peak power problems and blackouts caused by power failures. With the introduction of V2G in our society, the charging cost of EVs will be reduced greatly which will further influence the EV market. Consequently, it will serve as one step further towards green environment. Oil deficient countries such as Pakistan spend a lot of money in importing oil from the gulf countries, which is necessary but expensive as well. Therefore, EVs will prove provident in this regard and fuel consumption will be greatly reduced as electric vehicles will become increasingly popular. The electricity tariff and peak energy demand will be greatly reduced as well due to the PV based integrated V2G concept
Technical Details of Final Deliverable
The end product of our project will be a prototype of PV based integrated V2G charging station capable of bi-directional transfer of energy between grid and EV. Our prototype will show that the charging station, based on a DC microgrid, can operate well considering the EV charging/discharging behaviors; the proposed SPVA (Searching Peak and Valley Algorithm) will be highly effective in reducing the cost of the public grid by calculating the optimal start and operating time of EVs, while ensuring the stability of the public grid. Addition of PV will further enhance the stability of our charging station and decarbonize the environment.
