Due to the depletion of fossil fuels, coal, and oil, traditional electricity generation has a difficult task for utilities. A cheaper and more efficient method of doing this is required. A different source is required to fulfill the consumers power requirements. The alternate source should be sustainable and capable of meeting the consumers requirements. The integration of renewable energy into the grid is a useful way to fulfill demand. Renewable energy integration confronts three major problems frequency variation, power quality concerns, and power system instability. The following problems were of critical importance. An analytic hierarchy approach based expert system is utilized to identify and categorize power quality incidents. Before, it could sense things like sag, swell, transients, harmonics, interrupts, and flickers. An error free event classification system has been suggested. Simplified procedure allows for improved detection and categorization of power quality incidents. an investigation of power quality incidents and their mitigation using unified power quality conditioners UPQC An Adaptive Neuro Fuzzy Inference System ANFIS is used to minimize various power quality issues. Integrating renewable energy sources efficiently minimizes the environmental impact. The suggested method provides a solution to voltage unbalances and lowers overall harmonic distortion at the point of common coupling PCC . The addition of an ANFIS controlled DVR is used to reduce voltage irregularities caused by integrating renewable energy sources and faults in the transmission line. An artificial fault was added to power quality events with the goal of making use of renewable energy. To minimize the adverse effects of power quality incidents, the ANFIS controlled DVR proposal is in place. ANFIS controlled DVR is contrasted to a traditional technique of surveillance. Distributed static compensator D STATCOM is used to prevent voltage flickers, and total harmonic distortion, caused by nonlinear loads. D STATCOM is suggested to use three control methods Instantaneous power theory, Synchronous vector PI Control, and Harmonic elimination. Under extreme load circumstances, the D efficacy STATCOMs is evaluated. The suggested expert system and the bespoke power devices will be analyzed and discussed using various control techniques.

Traditional power production has become challenging for utilities due to the depletion of fossil fuels, coal, and oil. This must be done in a less expensive and more efficient manner. To meet the consumers power needs, a new source is needed. The alternative source should be sustainable and capable of fulfilling the needs of the customer. The incorporation of renewable energy into the grid is a helpful method of meeting demand. The integration of renewable energy has three main challenges frequency fluctuation, power quality issues, and power system instability. The following issues were critical in nature. An expert system based on an analytic hierarchy method is used to detect and classify power quality issues. Previously, it could detect sag, swell, transients, harmonics, interruptions, and flickers. A method for categorizing events that is error free has been proposed. The streamlined process provides for more accurate identification and classification of power quality issues. an examination of power quality issues and their mitigation via the use of unified power quality conditioners UPQC To reduce different power quality problems, an Adaptive Neuro Fuzzy Inference System ANFIS is employed. Using renewable energy sources effectively reduces environmental impact. The proposed technique corrects voltage imbalances and reduces overall harmonic distortion at the point of common connection PCC . The installation of an ANFIS controlled DVR is utilized to minimize voltage fluctuations induced by the integration of renewable energy sources and transmission line failures. With the aim of using renewable energy, a fake fault was introduced to power quality events. The ANFIS controlled DVR plan is in place to mitigate the negative impacts of power quality events. ANFIS controlled DVR is compared to a conventional surveillance method. Nonlinear loads generate voltage flickers and total harmonic distortion, therefore a distributed static compensator D STATCOM is employed to avoid these. It is recommended that D STATCOM use three control methods instantaneous power theory, synchronous vector PI control, and harmonic elimination. The D efficacy of STATCOMs is tested under severe load conditions. Various control methods will be used to evaluate and debate the proposed expert system and customized power devices.

1Wonders of the Jungle

By Sarath Kumar Ghosh

How do elephants drink? What is the Law of the Jungle at the water hole? How does an elephant baby learn to feed and learn to swim? How do they walk under water? In what order do buffaloes drink? How do buffaloes fight the tiger? These and other wild inhabitants of the Indian jungle such as pigs, wild dogs, deer, camels, bears and birds are discussed in lively stories to entertain but mainly educate children of school age. "One of the great thinkers of the world has said that all the sciences are embodied in natural history. Hence natural history should be taught to a child from an early age. Perhaps the best method of teaching it is to set forth the characteristics of animals in the form of a narrative. Then the child reads the narrative with pleasure and almost as a story, not as a tedious "lesson." In this book the animals are described in their daily life, and the main scientific facts and principles concerning each animal are woven into the narrative as a part of that daily life."
