Many countries have plans to deploy electric vehicle charging stations (EVCS ). As researchers, how do we start with that?, What about the expected issues that will occur in the power system and ways to solve them?.
In any country road network connected the areas or the load areas(citis) could be justified for charging station distribution depending on loading the transportation traffic. More industrial development of load area the city, means more charging stations 🚉 , accordingly charging station network could be justified.
Thank you Bhupendra Desai for the clarification. But what about the concept of vehicles-to-grid? I think we are still missing the inclusion of V2G methodology, especially in large-scale power systems.
EVs charge their batteries from the power grid and may cause severe effects if not managed properly. On the other hand, they can provide many benefits to the power grid and get revenues for EV owners if managed properly. A good overview of potential negative impacts of EVs charging on electric power systems mainly due to uncontrolled charging and how through controlled charging and discharging those impacts can be reduced and become even positive impacts is provided in the following paper.
Nour, M.; Chaves-Ávila, J.P.; Magdy, G.; Sánchez-Miralles, Á. Review of Positive and Negative Impacts of Electric Vehicles Charging on Electric Power Systems. Energies 2020, 13, 4675. https://doi.org/10.3390/en13184675
Free solar charging station like in Germany 🇩🇪 at factory could increased the factory efficiency with higher productivity with reduced power system loading …..
one should be familiar whit power electronic and components to design and make a EV chargers.it will be in the high power range as 100KW or more so he or she must be noticed.
the impact on power network will be harmonic-voltage sag-loss .
one should use capacitor and harmonic filter to improve the it's performance .
One of the known issues:
At night (when only wind power is available) people will want to charge their cars at home. During the day, the homes will provide solar power, but people will want to charge their cars at work in city centers.
How much investment is required to reinforce the distribution networks to allow this?
Is it possible or cheaper to use smart technology to provide flexibility?
Some more research topics:
Users have the objective of charging their own vehicles.
Service providers have the objective of maximizing profits
System operators have the objective of controlling frequency and voltage for the benefit of all users.
How can these objectives be reconciled - what sort of tariffs would help?
In emergency conditions, system operators may need to over-ride charging to avoid other load shedding
How can they communicate their needs to millions of EV chargers?
How can this be done securely and not by malicious actors?
Thank you Tom Berry for your further clarification about the EVCS situation. I am still trying to find significant solutions for all the issues you mentioned. I found many topics but I'm still confused to find something simple to start with.
