The augmentation in electricity demand, power system privatization as well as efficacy of renewable resources has paved the way for power system companies and researchers to exploit the field of grid connected distributed generation (DG) and its issues, islanding being a dominant one. Several research works have been conducted to mitigate the issues of islanding detection (ID). In context of this, the paper gives a comprehensive review of islanding issues, standard test systems, criteria and shifting of research trends in islanding detection methods (IDMs). The significant contributions pertain to categorization of IDMs, evaluation of non-detection zone (NDZ) for each test system, disquisition on evolution and advancement of IDMs and its comparisons based on criteria such as NDZ, run on time, nuisance tripping percentage, applicability in multi DG system and implementation cost to draw out the strength and shortcomings of individual methods that will come to aid to the companies or researchers for establishing the applicability and appropriateness of such method for their concerned domain.

Prevalent converters for induction heating (IH) applications employ two-stage conversion for generating high-frequency magnetic field, namely, AC to DC and then DC to high-frequency AC (HFAC). This research embarks upon a direct conversion of utility AC to high frequency AC with the design of a single-phase matrix converter (SPMC) as a resonant converter using a modified switching technique for IH application. The efficacy of the proposed approach is validated through different attributes such as unity power factor, sinusoidal input current and low total harmonic distortion (THD). The developed prototype-embedded system has high pragmatic deployment potential owing to its cost effectiveness using Arduino mega 2560 and high voltage/current as well as low switching time IXRH40N120 insulated-gate bipolar transistor (IGBT). Different results of the prototype-embedded system for IH application have been verified using Matlab Simulink environment to corroborate its efficacy.

The primary source of energy is depleting day by day owing to an increase in per capita energy consumption. To ensure energy security, to minimize climate change problems and to guarantee sustainable development, the useful utilization of renewable energy potential is of utmost importance. Recent researches reveal significant environmental effects in utilization of photovoltaic technology in large power plants located in urban locations. Further observations depict that the ground mounted PV power plants occupy large land spaces in the modern cities. These have led to the escalation of land price which has resulted in increasing the levelized tariff of electricity. Floating Solar Photovoltaic (FSPV) is an alternative to mitigate the aforesaid problems. In this article, a techno‐economic feasibility of a 10 MW FSPV plant is done to show the economic viability and environmental suitability in maintaining ecological balance through adoption of floating solar photovoltaic technology as compared to conventional ground mounted PV systems. The results show that floating solar photovoltaic power plant has 10.2% more generating capacity than land based PV system and producing 28.38 MU excess generation over the life cycle of the plant. The FSPV plant will save the land cost burden of USD 352125 and water cess burden of USD 47,600. This results in reducing the levelized tariff of FSPV plant to USD 0.026/kWh which is 39% less than land based PV power plant. The FSPV plant will also save 92,945.92 MT of Coal and a total CO2 emission of 340,801.74 ton. The FSPV power plant will help to bridge the gap between energy demand and supply along with reducing the cost of electricity and protecting the environment.
