WORKSHOP: Frequency Control Schemes and Frequency Response of Power Systems c...Francisco Gonzalez-Longatt
The frequency of a power system depends on real power balance: generation-demand. During the normal operation of a power system, the frequency is regulated within strict limits by adjusting the electrical supply to meet the demand. If the balance between generation and demand is not reached, the system frequency will change at a rate initially determinate by the total system inertia. The total system inertia comprises the combined inertia of most of spinning generation and load connected to the power system. The contribution of the system inertia of one load or generator depend if the system frequency causes change in its rotational speed and, then, its kinetic energy. Worldwide, electricity generation from renewable energy is increasing rapidly; it is especially true in terms of the increasing of the wind power penetration. This situation arise some issues regarding the system frequency control because wind turbines provide small or even none response to frequency changes. Power electronically controlled and/or power electronically connected generators such as DFIG and FPC wind turbines do not naturally provide inertia response. However inertia response can be emulated by adding a supplementary control signal proportional to the rate of change of frequency, this is named the Synthetic or Artificial Inertia. This approach imposes some challenges about control and protection systems. This workshop is designed to provide a general understanding of the frequency control schemes and frequency response of power systems with the integration of wind power penetration.

Design and Analysis of PID and Fuzzy-PID Controller for Voltage Control of DC...Francisco Gonzalez-Longatt
DC microgrids are desired to provide the electricity for the remote areas which are far from the main grid. The microgrid creates the open horizontal environment to interconnect the distributed generation especially photovoltaic (PV). The stochastic nature of the PV output power introduces the large fluctuations of the power and voltage in the microgrid and forced to introduce the controller for voltage stability. There are many control strategies to control the voltage of a DC microgrid in the literature. In this paper the proportional-integral-derivative (PID) and fuzzy logic PID (FL-PID) controller has been designed and compared in term of performance. Performance measures like maximum overshoot and settling time of FL-PID compared with the PID proved that the former is better controller. The controllers are designed and simulated in the MATLAB programming environment. The controllers has been tested for the real time data obtained from Pecan Street Project, University of Texas at Austin USA.

This report takes a look into the patenting activity around hybrid vehicles uncovering the inventors, the companies and the intellectual property history behind different drivetrain configurations, its research momentum and key intellectual property indicators.
A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.
A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle which combines a conventional internal combustion engine (ICE) propulsion system with an electric propulsion system.
Current HEVs reduce petroleum consumption under certain conditions, compared to otherwise similar conventional vehicles by using three mechanisms:
1. Reducing wasted energy during idle/low output by turning the ICE off.
2. Regenerative braking which is recapturing waste energy.
3. Reducing the size and power of the ICE.
This report focuses on how Patent data can help uncover the trends, gaps and opportunities that exist around this area. You will find the information on the research activity, existing & emerging trends in the different technological advancements in hybrid vehicle domain.
This report was prepared by mining patent data using Patent iNSIGHT Pro, a comprehensive patent analysis platform that helps one accelerate time-to-decision from patent analysis activities.

3) At the transmission level, smart grids use technologies like Flexible AC Transmission Systems and distributed autonomous control.
This report takes a look into the patenting activity around gallium Nitride uncovering the companies, inventors, and key applications.
GaN is a binary III-V direct bandgap semiconductor commonly used in LEDs. Its wide-band gap of 3.4 eV affords its special properties for applications in optoelectronic, high-power and high-frequency devices. Because GaN offers very high breakdown voltages, high electron mobility, and saturation velocity it is also an ideal candidate for high-power and high-temperature microwave applications like RF power amplifiers at microwave frequencies and high-voltage switching devices for power grids. Solutions that use GaN-based RF transistors are also replacing the magnetrons used in microwave ovens.
Gallium Nitride (GaN) transistor models have evolved from GaAs (gallium arsenide) transistor models; however there are many advantages GaN offers:
• Higher operating voltage (over 100-V breakdown)
• Higher operating temperature (over 150°C channel temperature)
• Higher power density (5 to 30 W/mm)
• Durable and crack-resistant material
GaN devices are often grown on SiC (silicon carbide) substrates, but to achieve lower-cost GaN devices, they can be grown on sapphire and silicon wafers. GaN’s wide bandgap allows for higher breakdown voltages and operation at high temperatures. The high thermal conductivity of SiC makes it a better substrate than silicon for power amplifier applications that require good heat sinking.
The document discusses how information and communication technologies (ICT) can help address climate change through various strategies such as relocating data centers to remote renewable energy sites connected by optical networks, virtualizing services to reduce physical infrastructure needs, and incentivizing reductions in carbon emissions through "carbon rewards" rather than penalties. It outlines pilots and examples of implementing these strategies and argues that a zero carbon approach is essential for sustainable growth of ICT.
Professor Tony Bendell's TOCICO Workshop Slidesaliciaandrews
The document describes a two-day workshop on anti-fragility and the Theory of Constraints hosted by Tony Bendell. Day 1 will introduce anti-fragility and answer how developing anti-fragility in an organization differs from a focus on robustness. Guest speakers will also present. Day 2 will explore the relationship between anti-fragility and the Theory of Constraints, guide an organizational assessment of fragilities, and help participants develop personal action plans to transform their organizations from fragile or robust to anti-fragile. The workshop aims to extend the Theory of Constraints model to account for links between flow and fragility in systems.

The total system inertia (H) is the primary source of electricity system robustness to frequency disturbances which arise due to an imbalance of generation and demand. The traditional large synchronous generators directly connected to the grid are the main sources of inertia, and they play an important role in limiting rate of change of frequency (ROCOF) and provide a natural response to the system frequency changes following an unscheduled loss of generation or demand from the power system.
The transition to a low carbon society is the driving force pushing the traditional power system to increase the volume of non-synchronous technologies which mainly use power converters (PCs) as an interface to the power network. The PCs decoupled the primary source from the power network, as a consequence are not able to contribute with “natural” inertia in the same way as classical synchronous generators. During a system frequency disturbance (SFD), the system frequency will change at a rate initially determined by the total system inertia (H). The inertial response of the system might be negatively affected with devastating consequences for system security and reliability.
The objective of this seminar is to present the fundamental aspects about system Frequency Control in Low Inertia Systems.
This seminar has special emphasis on non-synchronous technologies, mainly using power converters (PCs): (a) High Voltage DC (HVDC) and (b) Wind Power Integration and considers the implications on frequency control.

The total system inertia (H) is the primary source of electricity system robustness to frequency disturbances which arise due to an imbalance of generation and demand. The traditional large synchronous generators directly connected to the grid are the main sources of inertia, and they play an important role in limiting rate of change of frequency (ROCOF) and provide a natural response to the system frequency changes following an unscheduled loss of generation or demand from the power system.
The transition to a low carbon society is the driving force pushing the traditional power system to increase the volume of non-synchronous technologies which mainly use power converters (PCs) as an interface to the power network. The PCs decoupled the primary source from the power network, as a consequence are not able to contribute with “natural” inertia in the same way as classical synchronous generators. During a system frequency disturbance (SFD), the system frequency will change at a rate initially determined by the total system inertia (H). The inertial response of the system might be negatively affected with devastating consequences for system security and reliability.

Future Meshed HVDC Grids: Challenges and Opportunities, 29th October 2015, Po...Francisco Gonzalez-Longatt
This document provides a brief history of HVDC transmission systems from the late 19th century to modern applications. Some key points:
- Early systems in the late 1800s used DC transmission over long distances but were inefficient due to the need for rotating machinery.
- In the 1930s, mercury arc valves were used in experimental HVDC systems in the US and Germany.
- The first modern HVDC system using thyristor valves went into service in Sweden in 1950, transmitting 20MW over 98km.
- Major projects in the 1960s included the first cross-channel link between England and France and a 750MW, 450km overhead line in Russia.

The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.
