Power System Frequency Control: Modeling and Advances evaluates the control schemata, secondary controllers, stability improvement methods, optimization considerations, microgrids, multi-microgrids, and real-time validation required to model and analyze the dynamic behavior of frequency in power systems. Chapters review a range of advanced modeling and analytical considerations for single to multi-area networks using traditional and hybrid sources, including renewable sources, FACT devices and storage. The work also considers broad aspects of upstream and downstream control mechanisms which enable novel solutions in the area of automatic generation control in power system networks. Highly recommended for power system engineers, researchers and practitioners with interests in load frequency control, automatic generation control, linearized models of isolated microgrid, and multi-microgrid, and hybrid LFC scheme, this book is an ideal resource on the topics discussed.

Use of microtuber is advantageous than microplants but dormancy problem of microtuber limits its production and use in the laboratory and the field respectively. This book provides a proven solution of dormancy breaking of freshly harvested microtuber with 5 to 7 days. A series of experiments in relation to production and breaking of dormancy of potato microtubers were conducted during 2000-2003. Nitrogen at 45 and 60 mM with 300-500 mg/l CCC or 30-50 mg/l coumarin or 5 mg/l BAP or 10% sucrose produced higher proportion of large size (>200 mg) microtubers after 105 days. Treatment of intact microtuber with GA3 (0, 5, 10 and 15 mg/l) did not show any noticeable effect on dormancy breaking, while soaking of peeled microtubers treated with 0.1-1.0 mg/l GA3, 0.1 to 1.0 mg/l IAA and 0.01 to 0.1 mg/l Kin for 1 to 25 min and put on water soaked cotton pad containing in petriplates showed >90% sprouting within 7 days. Suberisation of peeled microtubers after treatment had no effect on sprouting but was safe from rot, while no rot of microtuber was observed while handling aseptically. This book would be useful for the tissue culture laboratory as well as basic seed potato growers.

Chilli (C. annuum and C. frutescens) is one of the most important spice crops in Bangladesh as well as in the world. The genotypes of chilli under investigation showed considerable variation in most of the characters. The best dose of NPK per hectare were 100, 60, 100 or 125, 60, 100, respectively as in most cases these doses gave the best result for obtaining the maximum yield and these two doses were identical in most of the cases. 125 kg N, 60 kg P and 100 kg K was the best dose for getting highest gross return, net return and BCR and this dose was also identical to 100 kg, 60 kg and 100 kg per hectare NPK, respectively. The best dose of S, Zn and B per hectare was found to be 20 kg, 3 kg and 1.5 kg, respectively for getting the highest yield and highest BCR. To get the highest seed yield 100 kg N, 60 kg P and 100 kg K per hectare along with 20 kg S, 3 kg Zn, 2 kg B per hectare were found the best dose.
