This document proposes using a static compensator (STATCOM) connected to a battery energy storage system (BESS) to mitigate power quality issues from wind energy generation. Wind power fluctuates due to changing wind speed, which affects power quality. The STATCOM injects reactive power from the BESS to absorb harmonic current and regulate voltage. This improves power quality by making the source current harmonic-free and stabilizing the system voltage. The combination of BESS and STATCOM helps compensate for wind power fluctuations and produces higher quality power from the wind generation system.

The general trends in the past decade of increasing solar cell efficiency, decreasing PV system costs, increasing government incentive programs, and several other factors have all combined synergistically to reduce the barriers of entry for PV systems to enter the market and expand their contribution to the global energy portfolio. The shortcomings of current inverter functions which link PV systems to the utility network are becoming transparent as PV penetration levels continue to increase. In this paper an analysis of solar system connected with the grid has been done. The system is subjected with two types of perturbations, i.e. variable load and the variable irradiance level which changes the output of the solar system. The design, modeling, and analysis of a grid-tied PV system are performed in the MATLAB software simulation environment.

Simulation and Analysis of a D-STATCOM for Load Compensation and Power Facto...IJMER
Power Generation and Transmission is a complex process, requiring the working of many
components of the power system in tandem to maximize the output. One of the main components to form
a major part is the reactive power in the system. It is required to maintain the voltage to deliver the
active power through the lines. Loads like motor loads and other loads require reactive power for their
operation. To improve the performance of ac power systems, we need to manage this reactive power in
an efficient way and this is known as reactive power compensation. In developing countries like India,
where the variation of power frequency and many such other determinants of power quality are
themselves a serious question, it is very vital to take positive steps in this direction.
The work presented here illustrates a method to compensate for the load reactive power using a

The system contains a DSTATCOM connected in parallel to regulate voltage and correct power factor as loads change. Simulation results show the DSTATCOM improves power quality by correcting power factor, balancing loads, and regulating voltage under different load conditions using both PI and fuzzy logic controllers. The presentation concludes fuzzy logic control of a DSTATCOM is effective for power quality improvement in small isolated power systems like ships, islands, and remote generation sites.
STATCOM for Improved Dynamic Performance of Wind Farms in Power Grid IJMER
Application of FACTS controller called Static Synchronous Compensator STATCOM to
improve the performance of power grid with Wind Farms is investigated .The essential feature of the
STATCOM is that it has the ability to absorb or inject the reactive power with power grid. Therefore,
the voltage regulation of the power grid with STATCOM FACTS device is achieved. Moreover restoring
the stability of the power system having wind farm after occurring severe disturbance such as faults or
wind farm mechanical power variation is obtained with STATCOM controller. The dynamic model of
the power system having wind farm controlled by proposed STATCOM is developed. To validate the
powerful of the STATCOM FACTS controller, the studied power system is simulated and subjected to
different severe disturbances. The results prove the effectiveness of the proposed STATCOM controller
in terms of fast damping the power system oscillations and restoring the power system stability.
Unified power quality conditioner for compensating power quality problem adIAEME Publication
This document describes a proposed Adaptive Neuro-Fuzzy Inference System (ANFIS) based Unified Power Quality Conditioner (UPQC) to improve power quality compensation performance. A UPQC uses two voltage source inverters to compensate for both voltage and current disturbances but has high DC link capacitor discharge times. The proposed system adds an ANFIS device to generate a bias voltage that maintains the DC link voltage at a lower level. ANFIS combines neural networks and fuzzy logic to approximate nonlinear functions from numerical and linguistic data. The generated fuzzy rules are trained using a neural network to produce the desired output. Analysis shows the proposed ANFIS-based UPQC provides better power quality compensation than controllers using neural networks,
Integration of upqc for power quality improvement in distributedNagaraj Madival
This document reviews research on integrating a Unified Power Quality Conditioner (UPQC) in distributed generation networks. A UPQC can compensate for voltage disturbances, current harmonics, reactive power, and power factor issues. Two main integration techniques are discussed: 1) Connecting distributed generators to the UPQC's DC link, which allows voltage interruption compensation and active power transfer but with higher control complexity. 2) Having separate UPQC and distributed generator systems, which is easier to control but may not provide voltage interruption compensation or islanding mode operation. The document also discusses using a UPQC across two distribution feeders to maintain constant voltages during faults or interruptions.
A Svc Light Based Technique for Power Quality Improvement for Grid Connected ...IOSR Journals
This document presents a SVC light based technique for improving power quality in a grid-connected wind energy system. The technique uses a STATCOM device called SVC light connected at the point of common coupling to address various power quality issues caused by the connection of wind turbines to the grid, including voltage fluctuations, harmonics, reactive power absorption, and fault ride-through capability. The proposed control scheme aims to maintain unity power factor at the source, provide reactive power support from the SVC light, and reduce harmonic distortion. Simulation results show the SVC light is able to regulate the grid voltage, compensate reactive power demand, and cancel harmonic currents, improving the overall power quality when integrated with the wind and load.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
