Different Electric Vehicle Charging Strategies to avoid Reducing the Insulation Oil Lifetime of Distribution Transformers

Impacts of Electric Vehicle Charging on Electric Power Distribution Systems

Electric Vehicle Charging Modeling

With an electrified passenger transportation fleet, carbon dioxide emissions could be reduced significantly depending on the electric power production mix. Increased electric power consumption due to electric vehicle charging demands of electric vehicle fleets may be met by increased amount of renewable power production in the electrical systems. With electric vehicle fleets in the transportati...

Metaheuristic Optimization of Electric Vehicle Charging Strategies in Uncertain Environment

Probabilistic power flow studies form essential investigations for both operation and analysis of electric power grids under stochastic conditions. Especially the increasing penetration of intermittent and non-dispatchable power plants like wind power plants cause probabilistic behaviour at the supply side. At the same time, the expected penetration of electric mobility at the demand side compl...

Multi-Objective Distribution Network Expansion Incorporating Electric Vehicle Charging Stations

Abstract: The paper develops a multi-objective planning framework for distribution network expansion with electric vehicle charging stations. Charging loads are modeled in the first place, and then integrated into the optimal distribution network expansion planning. The formulation is extended from the single objective of the economic cost minimization into three objectives with the additional ...

Solid insulation drying of 110 kV paper-oil instrument transformers

Influence of moisture on the instrument transformers’ paper-oil insulation and its further maintenance is described in this paper. Improved insulation drying method using vacuum and temperature regulation with definite regulation algorithm of parameters is proposed and analyzed by comparing it with conventional drying method.
