Introduction 1

The energy sector is moving into the era of distributed generation (DG) and microgrids (MGs). The stability and operation aspects of converter-dominated DG MGs, however, are faced by many challenges. To overcome these difficulties, this paper presents a new large-signal-based control topology for DG power converters that is suitable for both grid connected and islanding modes of operation without any need to reconfigure the control system and without islanding detection. To improve MG stability and to guarantee stability and high performance of the MG system during sudden harsh transients such as islanding, grid reconnection, and large load power changes, a nonlinear MG stabilizer is proposed. We propose a novel control topology for microgrids which can work in both grid connected and islanding modes without reconfiguration so it does not require islanding detection technique, the controller is based on the concept of synchronverter In this paper, a radical step is taken to improve the synchronverter as a self-synchronized synchronverter by removing the dedicated synchronization unit

Neuro Fuzzy Inference System (ANFIS) controlled modified Unified Inter-Phase Power Controller (UIPC). For study, a classic hybrid micro-grid connected to grid comprising of a AC micro-grid and a DC micro-grid is taken into account. These micro-grids are interconnected employing a modified UIPC, rather than using the power converters connected in parallel. As the first input of this paper is the standard structure of UIPC, which used three power converters in every phase. It was then modified such as number of power converters is used less and implemented for the control of the exchange of power between AC-DC microgrids. In every phase there is one power electronic converter in the improved structure. It is called as Line Power Converter (LPC). Also there is Bus Power Converter (BPC) to regulate the voltage of the DC bus. The Line Power Converters links the AC micro-grid to the main grid. The DC buses are also linked with them. It can be operated in Inductance Mode (IM) as well as Capacitance Mode (CM). The control structure of LPCs has an Adaptive Fuzzy Logic Controller in it. For hybrid micro-grids, the capability of the suggested power flow control strategy is confirmed by the MATLAB simulation results.

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.

Como certa revista disse: “vivemos em tempos de ansiedade, “tempos críticos, difíceis de manejar.Muitos ficam abalados por crises econômicas, problemas familiares, guerras, doenças mortíferas e desastres naturais ou de origem humana. Como se isso não bastasse, todos temos preocupações pessoais como: ‘Será que esse tumor é um câncer?’ ‘Em que mundo meus netos vão viver?’ Nem toda ansiedade é ruim. É normal sentir estresse antes de uma prova, de uma apresentação ou de uma entrevista de emprego. E um medo saudável do perigo pode nos impedir de colocar nossa vida em risco. Mas a ansiedade extrema ou constante é devastadora. Estudos recentes envolvendo mais de 68 mil adultos revelaram que até mesmo uma leve ansiedade aumenta o risco de morte prematura“ . Como citado acima, fatores de várias ordens podem afetar o homem de muitas formas, com isso impactando seu desempenho no trabalho

Adiabatic describe the thermodynamic processes in which there is no energy exchange with the environment, and therefore very less dissipated energy loss. These circuits are low power circuits which use reversible logic to conserve energy. Adiabatic logic works with the concept of switching activities which reduces the power by giving stored energy back to the supply. The main design changes are focused on power clock which plays the vital role in the principle of operation. This has been used because many adiabaticcircuits use a combined power supply and clock, or a power clock (Four Phase).To achieve this, the power supply of adiabatic logic circuits have used time varying voltage charging signal, in contrast to traditional non-adiabatic systems that have generally used constant voltage charging from a fixed-voltage power supply. Thereby the circuit topology and operation of the circuit has been changed so that the source current of CMOS transistor change its direction and goes back to the supply(Recovery) when the power clock falls from VDD to zero. Power efficient blocks can be designed by using adiabatic logic which can be used in combinational and sequential circuits. The simulation of the designs is done using a backend tool called MENTOR GRAPHICS in 130nm technology

Most of the PV systems are designed with transformer for safety purpose with galvanic isolation. However, the transformer is big, heavy and expensive. Also, it reduces the overall frequency of the conversion stage. Generally PV inverter with transformer is having good efficiency. To overcome these problems, transformer less PV system is introduced. It is smaller, lighter, cheaper and higher in efficiency. However, dangerous leakage current will flow between PV array and the grid due to the stray capacitance. There are different types of configurations available for transformer less inverters like H5, H6, HERIC, and Dual paralleled buck inverter. But each configuration is suffering from its own disadvantages like high conduction losses, shoot-through issues of switches, dead-time requirements at zero crossing instants of grid voltage to avoid grid shoot-through faults and MOSFET reverse recovery issues. The main objective of the proposed transformer less inverter is to address two key issues: One key issue for a transformer less inverter is that it is necessary to achieve high efficiency compared to other existing inverter topologies. Another key issue is that the inverter configuration should not have any shoot-through issues for higher reliability.

The input sources for the system are solar panels and wind energy conversion systems (WECS), each equipped with a Landsman converter. The WECS and solar panels are connected to the input DC line. To store energy, a bidirectional DC/DC converter and battery are connected to the DC bus. The dsPIC microcontroller is its ability to generate Pulse Width Modulation (PWM) signals, which are used to provide the gate pulse to the Landsman converter and single-phase voltage source inverter.

Emergency back-up power supply units are necessary in case of grid power shortage, considerably poor regulation and costly establishment of a power system facility. In this regard, power electronic converters based systems emerge as consistent, properly controlled and inexpensive electrical energy providers. This paper presents an implemented design of a grid-tied emergency back-up power supply for medium and low power applications. There are a rectifier-link boost derived DC-DC battery charging circuit and a 4-switch push-pull power inverter (DC-AC) circuit, which are controlled by pulse width modulation (PWM) signals. A changeover relay based transfer switch controls the power flow towards the utility loads. During off-grid situations, loads are fed power by the proposed system and during on-grid situations, battery is charged by an AC-link rectifier-fed boost converter. Charging phenomenon of the battery is controlled by a relay switched protection circuit. Laboratory experiments are carried out extensively for different loads. Power quality assessments along with back-up durations are recorded and analyzed. In addition, a cost allocation affirms the economic feasibility of the proposed framework in case of reasonable consumer applications. The test-bed results corroborate the reliability of the research work.

The integration landscape is changing rapidly with the introduction of technologies like GraphQL, gRPC, stream processing, iPaaS, and platformless. However, not all existing applications and industries can keep up with these new technologies. Certain industries, like manufacturing, logistics, and finance, still rely on well-established EDI-based message formats. Some applications use XML or CSV with file-based communications, while others have strict on premises deployment requirements. This talk focuses on how Ballerina's built-in integration capabilities can bridge the gap between "old" and "new" technologies, modernizing enterprise applications without disrupting business operations.
