Abstract.Recently smart demand side management (DSM) is a very important tool that permits customers to take right decisions for their energy consumption and helps the energy utilities to decrease the over load demand and reshape the load curve. This paper proposes an optimized DSM technique based on smart metering uses different techniques such as load shifting and peak clipping to minimize domestic power consumption especially during load peaks. A new optimization technique (Bat Algorithm) is applied on proposed system and then compares results with other optimization techniques (Genetic Algorithm and Interior point Algorithm) to optimize the minimum consumption during peak hours according to load type. A control algorithm is applied to the proposed system to achieve the load shifting and load clipping according to the optimization results.

“…Generally, the charging schemes consist of CC charging until the EV battery voltage reaches the charge voltage level, then CV charging is applied, allowing the charge current to taper until it becomes a very small value. It is recommended to follow the charging current during the charging process, which represents the ideal current at which the battery should be charged initially (to roughly 70% of state-of-charge) under the CC charging scheme before transitioning into CV charging scheme [32,33].…”

This paper presents the control and simulation of an electric vehicle (EV) charging station using a three-level converter on the grid-side as well as on the EV-side. The charging station control schemes with three-level AC/DC power conversion and a bidirectional DC/DC charging regulator are described. The integration of EVs to the power grid provides an improvement of the grid reliability and stability. EVs are considered an asset to the smart grid to optimize effective performance economically and environmentally under various operation conditions, and more significantly to sustain the resiliency of the grid in the case of emergency conditions and disturbance events. The three-level grid side converter (GSC) can participate in the reactive power support or grid voltage control at the grid interfacing point or the common coupling point (PCC). A fuzzy logic proportional integral (FL-PI) controller is proposed to control the GSC converter. The controllers used are verified and tested by simulation to evaluate their performance using MATLAB/SIMULINK. The comparison of a PI-controller and a PI-Fuzzy controller for the EV charging station shows the effectiveness of the proposed FL-PI controller over conventional PI controller for same circuit operating conditions. A good performance for PI-Fuzzy in terms of settling time and peak overshoot can observed from the simulation results.

Climate change is mainly attributed to the burning of fossil fuels. To solve the problem, current inhabitants have to dispense with fossil fuels as a source of power. It has been demonstrated that this can be secured before 2050 by transitioning to renewable sources of energy. Massive energy storage (MES) incorporated into long distance high voltage direct current (HVDC) transmission systems is the key technology for the transition. This paper describes the current state-of-the-art in electricity grid configurations. It demonstrates how MES, and other back-up local electricity storage schemes represent a natural way of buffering electricity consumers from the intermittency of inherent in the primary renewable systems. Consequently, it can solve the base-load issues and facilitate a global transition to 100% renewable energy sources over the next fifteen to twenty years.
