Energy system designers and operators are more and more specializing in bettering the combination of a number of EVs and intermittent renewable vitality sources (RER), as a part of a transfer in direction of trendy microgrids. Nonetheless, such microgrids are more likely to encounter extreme challenges by way of elevated energy loss, thermal loading, voltage deviation, and general system value.
Now, a world group of researchers from Egypt, the United Arab Emirates, and Finland have proposed an environment friendly planning methodology, the “jellyfish search optimizer” (JSO) methodology, to unravel the EV allocation downside. charging station and RER in multi-microgrids. .
Completely different eventualities are investigated, together with the optimum integration of EV charging stations with out RERs, the optimum integration of EV charging stations and RERs with a managed charging technique, and the optimum integration of EV charging stations and RERs with have managed charging and discharging methods.
One of the best outcomes are obtained within the case of optimum integration of EV charging stations and RERs with a managed charging and discharging technique, the place the voltage deviation, vitality not offered, and the whole value are considerably lowered from within the base case. The researchers additionally discovered that the proposed optimizer can scale back working prices for RERs and standard stations whereas rising the capability of charging stations. This makes the JSO methodology superior for fixing the issue of allocation of EV charging stations and RERs in comparison with different well-known algorithms, the researchers stated.
They introduced their findings in “Multi-objective optimum planning of EV charging stations and renewable vitality sources for good microgrids,” which was just lately revealed in Power Science and Engineering.
