Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

2. Are you concerned with the reliability of your system grounding? The NGRM700 is
a sophisticated device that allows continuous NGR monitoring to provide peace of
mind that the power system grounding is intact.
The NGRM700 neutral grounding resistor monitor measures the resistance of the
NGR for High Resistance Grounded Systems (HRG). Its monitoring capabilities
include NGR current, voltage and continuity, phase-to-ground voltage. The ideal
relay to protect the grounding system and to provide main or backup ground-fault
detection. The relay can connect to a communications network and stores data
onboard for local or remote viewing.
The NGRM700 allows the user to meet their local code requirements including the
proposed 2018 CSA Section 10-302 - which requires detection of a ground fault on
the conductor connecting the NGR to the source and of loss of continuity of the
impedance grounding circuit for any impedance-grounded circuit used.
The better tool

grounding resistors
3. Early detection enhances operational
safety and maintenance planning
Resistance-grounded systems use current
transformer based ground-fault detection.
An open grounding resistor renders these
systems inoperable. Early detection of
an NGR problem provides the ability to
plan repair and indicates a previously
unknown hazard.
The NGRM700 allows using already
existing CTs and coupling devices for
more easy retrofit on site.

an integrated web server. This enables information display and setting adjustment on
a PC or a mobile device.
Interfaces
The integrated Ethernet interface supports data exchange within the Bender
product portfolio (BCOM) and with third-party devices or software packages
(Modbus TCP). Configurable analog outputs allow easy exchange of status information
or measured values.
Harmonic Analysis of NGR Current and Voltage
• Monitor systems with variable-frequency drives, power conversion, etc.
• Bar-graph spectrum analysis on HMI display (I and V) and comms output

AC and DC ground-fault detection
System Settings
The device can be adapted to the customer-specific application by setting all
relevant parameters. The customer can choose between different trip options, i.e.
on which signal the device should trip, either on RMS, Fundamental or Harmonic
window. After setting all relevant parameters the device will perform a calibration
on the installation to achieve the maximum accuracy.

7. The NGRM700 offers two HMI mounting options (FP200-NGRM):
• The FP200-NGRM HMI mounted in the NGRM700 chassis
• The display can be easily detached for mounting in a front panel
The display unit FP200-NGRM is mounted through a door using plastic tabs or the
screw mounting hardware. It is connected via a provided RJ45 connection cable to
the NGRM700. This installation variant makes it possible to install the display of the
device in the control cabinet front without having to order any additional parts.
9. Fast and easy ground-fault location
The NGRM indicates ground-fault occurence and phase voltages. When a fault occurs
it can be used to activate a pulsing ground-fault location system. Combining the
NGRM700 with RCMS multi-channel ground-fault relays can provide a quick method
of determining the location of the fault.
No matter what the system size add additional RCMS units to provide quick indication
of the faulted feeder or loads and have indication of fault location before electricians
are sent to repair.

RCMS460 versions provide indication of fault location via communications.
RCMS490 versions provide local and remote indication of fault location. Additional
single function or hand-held detectors can be used to further refine the search for
the fault. The RCMS490 output may also be used to control a local breaker if tripping
of the faulted load is preferred.
10. For even the
harshest
environments
Each electrical installation has its own requirements.
Increased climatic and mechanical requirements
The NGRM700 has conformally coated circuits and is suitable for extreme
operating conditions from -40 to +70 °C.
