This research investigates how distributed energy resources (DERs) and electric
vehicles (EVs) affect distribution networks. With sensitivity analysis, the
research focuses on how these integrations affect load profiles. The research
focuses on sizing of various DERs and EV charging/discharging strategies to
optimize the load profile, voltage stability, and network loss minimization.
System parameters including load profile, EV charging pattern, weather
conditions, DER sizes, and electricity pricing are analyzed to quantify their
individual and combined impacts on load variability. However, with increased
capacity of DERs, network losses increase. A mathematical model with system and
operational constraints has been developed and simulated in MATLAB Simulink
environment, validation of the proposed approach in improving the load profile,
and reduction in network losses, with the intermittent power generation from
DERs and EV integration. Simulation result shows that optimal capacity of DERs
and optimized EV integration improve the load profile, improve voltage
regulation at various nodes across the distribution network and reduction in
network losses considerable.
