For the sample IEEE 33-bus system, bus 2 is identified as having the highest index and therefore being the optimal location. A procedure is also provided to calculate the optimal size of the DG unit based on equations involving branch currents and voltages. The goal is to minimize losses and improve the voltage profile through optimal DG placement and sizing.
A Comprehensive Review of Protection Schemes for Distributed Generation
Due to the increasing demand of energy and the need for nonconventional energy sources, distributed generation (DG) has come into play. The trend of unidirectional power flow has been gradually shifting. With new technology comes new challenges, the introduction of DG into the conventional power system brings various challenges; one of the major challenges is system protection under DG sources. These sources pose a significant challenge due to bidirectional flows from DGs as well as lower fault current contribution from inverter interfaced DGs. This paper reviews existing protection schemes that have been suggested for active distribution networks. Most of these protection strategies apply only to smaller distribution systems implying that they may need to be extended to larger systems with a much higher penetration of distributed generation. In the end, a potential protection scheme has also been recommended as a future work.

An electric power system is a network of electrical components used to supply, transmit, and use electricity. It consists of interconnected power plants, transmission lines, and distribution facilities. Transmission lines carry power long distances from plants to areas of use as commercial, residential, or industrial loads. They form larger networks so failure of one line doesn't disrupt power. Power is usually transmitted as alternating current at high voltages for efficiency and easy voltage conversion.

Impact of Distributed Generation on Energy Loss
The aim is to give more insight into the effect of distributed power generation on energy loss. In most cases these distributed generators (DGs) are based on renewable energy such as solar panels and wind turbines, but there are also new technologies to increase efficiency such as the micro combined heat and power systems. Distributed generation can increase efficiency in the grid by reducing the distance between generators and consumers of electricity. The objective is to find an optimal mix of distributed generators (DGs) in a district so that energy loss is minimized and overload is avoided. The effect of using future electronic devices, such as electric vehicles, is also studied. To find an optimal mix of DGs a mixed integer quadratic programming model is defined and a case study is presented. The results indicate that the optimal solutions give substantial reductions in loss without overloading the system.

Examples on load curve
Here are the steps to solve this homework problem:
1) To draw the load curves and load duration curves, list the loads from each region in descending order. Plot these on two sets of axes to show regions A and B separately, and on a third set of axes to show the total loads.
2) To find the average load and load factor of the total system:
- Calculate the total load at each time interval by adding regions A and B
- Calculate the total area under the load curve by summing the load × time intervals
- Divide total area by total hours to get average load
- Calculate load factor as average load/max load
3) The reserve capacity is the plant capacity (10 MW
Load factor and demand factor
The document discusses key terms related to electrical power generation and load curves. It defines terms like connected load, demand factor, load factor, diversity factor, coincidence factor, loss factor, plant capacity factor, utilization factor, plant use factor, base load, and peak load. Load curves plot the variation in load over time and are important for understanding energy generation and demand. Base load refers to the minimum required electricity demand while peak load is the time of high demand.
Ohm's law
Ohm's law describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Voltage is the "push" or pressure behind current flow, measured in volts. Current is the quantity of electrical flow through a circuit, measured in amps. Resistance opposes the flow of current and is measured in ohms. Ohm's law can be expressed as formulas to calculate voltage, current, or resistance when two of the three values are known.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
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%.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

- 1. Chapter 6 Captive power plant (Electric Power Generation) By D. N. Thakkar RCTI, Ahmedabad.
- 4. • A captive power plant is a facility that provides a localised source of power to an energy user. These are typically industrial facilities, large offices or data centres. The plants may operate in grid parallel mode with the ability to export surplus power to the local electricity distribution network. Alternatively they may have the ability to operate in island mode; i.e. independently of the local electricity distribution system.
- 5. • Benefits of captive power plants • Security of power supply and resilience through self-generation • Reduced costs through high fuel efficiency, particularly when in CHP configuration • Improved environmental performance resulting from fuel efficiency
