Optimization and Validation of Distributed Generation Integrated Load Flow Scheme for Congestion Management of Interconnected Transmission Systems | Chapter 4 | Research and Developments in Engineering Research Vol. 9

 In reaction to scheduled or unscheduled disruptions, energy supply institutions extensively employ delivered generators (DG) to fulfil raised power demands. The expansion of broadcast and distribution networks, coupled with line interruptions, donates significantly to transmission line blockage within pertain systems. Addressing and mitigating blockage is essential for ensuring the reliable and adept operation of a power network. This branch explores the potential of delivered generation (DG) to alleviate blockage within interconnected broadcast systems. It places significant importance on devising a dependable approach to decide the optimal positions and sizes for integrating local generators to responsibility congestion, as it is a crucial necessity. The research aims to develop a straightforward and reliable strategy for the installation and sizing of DGs within a broadcast line system, utilizing capacity flow analysis. The initial reasoning is conducted on the 14-transport IEEE system to identify limits for assessing congestion asperity and determining the ideal DG locations and sizes. Load flow algorithms in ETAP program are utilized to assess capacity flows under various line interruption scenarios in the 14-bus IEEE order. The results indicate that the percentage breach of the system is a critical limit for evaluating blockage in interconnected systems. The study further checks the application of two indices, the Severity Index (SI) and Sensitivity Factor (SF), to recognize the optimal DG placement and volume for congestion relief. A reliable algorithm established these indices is proposed to guide DG installation and sizing decisions. This methods is grounded in whole indices and relies on load flow study. The proposed algorithm offers expeditious and accurate simulation results accompanying minimal approximations, ensuring inclusive optimal resolutions within a shorter imitation time and enhanced union probability, leveraging a mathematical approach. The practicability of this projected methodology for determining optimum DG placement and quantification in blockage solutions is assessed utilizing a practical pertain bus system inside the Kerala grid. This methodology is movable and can be adopted by broadcast system operators in related connected wholes worldwide. It effectively labels severe congestion cases and advises the best locations and sizes for DGs to survive congested feeders inside the grid system. Finally, the study of system losses for differing DG penetration scenarios through load flow study validates the acquired results.

Investigation on Electronically Coupled Distributed Generation Modeling and Control Strategies for Microgrid Applications| Chapter 2 | Current Topics on Mathematics and Computer Science Vol. 4

 A single-stage power converter capable of both maximum power point tracking and unity power factor dispatching is proposed for electronically coupled dispersed generation. Modeling a solar array (the dispersed generator) and a three-phase grid-connected inverter yields the best control parameters. Inner and outer control loops are used by the inverter's controller to control parameters. The inner control loop translates input from the abc frame to the d, q, 0 frame in order to dispatch at unity power factor. The new technique, which may be used at the primary control level in microgrid applications, tracks the maximum power point in the outside circuit. loop of voltage control (local controller). The active power of single-stage and two-stage power converters is compared, revealing that single-stage is more efficient. In terms of active power yields, a comparison is made between variable and fixed DC reference voltages for the proposed single-stage converter system. The impacts of diverse ambient disturbances on active and reactive power yields, such as changing weather conditions, solar radiation with severe disturbances, and varying PV cell temperature, are explored in this paper. this project A dynamic reference voltage is advised for use. Simulations in Matlab/Simulink demonstrate its efficiency under a variety of radiation and temperature settings. The single-stage power conversion system executes all duties correctly with a unity power factor operation.

Recent Study on Optimal Economic Dispatch in Microgrids with Renewable Energy Sources| Chapter 3 | New Insights into Physical Science Vol. 8

 The use of microgrids receives more interest in the scientific community due to the opening of the energy market and the agreements for the reduction of pollution emissions, but the management of the delivery of electricity has new challenges. As a main component of designing a microgrid, this paper considers various distributed generation systems and the management of resources is described over a period through the proposed dynamic economic dispatch approach. The inputs are obtained by the model predictive control algorithm, taking into account variations in both the consumption trend and the capability of generation systems, including traditional and renewable energy sources. In addition , the proposed solution considers a consumer benefit programme involving the limitation of demand and the regeneration costs of the pollutants generated by traditional generating systems. Via a mathematical programming approach, the dispatch strategy aims to minimise to the minimum the fuel costs of traditional generators, the energy transactions, the regeneration of polluted emissions and, eventually, includes the advantage of reducing electricity demand by mathematical programming strategy, fulfilling all constraints. LINGO 17.0 programme (Lindo Systems, 1415 North Dayton Street, Chicago, IL , USA) implements the model. The findings show the suggested approach efficacy under various considerations through a study case. Improving the operation of the analysed microgrid is accomplished because various variables and potential scenarios of loads and renewable energy production capability are included in the proposed problem formulation. The results obtained by the proposed algorithm in 24 review periods during the study interval ensure that the performance adjustment level of each microgrid generator can be specified at the best possible value.

Studies on a Probe into Reactive Power Management in Renewable Energy System Using Facts Devices | Chapter 6 | Recent Developments in Engineering Research Vol. 3

 

In the modern era, most of the utility grid is connected with Renewable Energy resources (RERs).
Many of the power electronic converters and reactive power compensating devices are also
incorporated into the existing grid making the system more complicated. The penetration of renewable
energy resources may affect grid stability, quality of power, reactive power balance and Sufficient
energy utilization. The Distributed Generation (DG) towards the power electronic interface creates
some critical power quality events such as reactive power management, harmonics and voltage
profile which makes the distributed system become a polluted one. The hiking demand for decarbonized energy supply leads to generate more distribution networks. This paper depicts the review of modelling and incorporation of various reactive power compensating devices like TCSC, SVC and STATCOM into RES. Power generation model of solar, wind and fuel farm is discussed in this paper. Reactive power compensating devices and its location and sizing are important for the stable and secure operation of the electric grid. Consequently, power quality issues, real-time interconnection issues and policies related to reactive power management are in this paper.
