At times, emergency load shedding is required based on predicted load in next interval. Under such situations, the load shedding strategy must be planned in anticipation and may be implemented after the load increase or in previous interval itself. In view of this, the paper presents a methodology for optimal load shedding in advance such that operating constraints are satisfied in the present condition and in the next interval predicted load condition. The effect of distribution generation has been considered. Sine-cosine optimization technique has been employed to get minimum load shedding at minimum buses. The algorithm has been implemented on a 14-bus standard test system.

The target of the programmed age control (Automatic Generation Control, AGC) is to direct the yield intensity of the electrical generator within an endorsed territory because of the deviation in recurrence and tie-line control. The paper presents AGC of two regions? traditional framework with sun-oriented warm power plant in one of the territories. A novel optimization, i.e., Jaya algorithm, is used for AGC control of power framework with or without solar energy. Jaya algorithm is fast convergent for controller gain of the Proportional-Integral-Derivative (PID) controller. The performances of Integral (I), Proportional-Integral (PI) and PID controller with Solar Thermal Power Plant (STPP) are evaluated. The results reveal that the PID controller provides better results than I and PI. The Jaya optimized PID with STPP gives better dynamic performance such as settling time, overshoots and undershoots as compared to the thermal power system.

At present, automation is common in commercial and domestic applications. In the current state of affairs, automation is not only about controlling things when the users are physically present at that exact place, it specifically means that they can control it from any place within the world. The paper presents web-based home automation with fault detection and monitoring approach. A nodeMCU board is employed as a brain of this method and to establish a connection with the internet. Together with that, a current sensor is employed for fault exploration and monitoring the activity of the appliance. Current is a governing parameter in the electricity world. Each appliance works properly for a selected worth of current. Further, a relay board is employed to regulate the appliances. Thus, in this paper, an infrequent approach is introduced to show the current status of the appliances, that it is on/off. And it additionally provides manual operative approach together with IoT-based automation by coordination of various relays.

Hearing impairment is a commonly observed human health problem across the world. In "hearing loss", hearing sensitivity is reduced. To treat hearing loss problem, hearing assistive devices are used. Hearing aids restore hearing ability for those having hearing problems. But with today's most advanced technologies in hearing aids, patients still have some difficulty in understanding speech in crowded areas. Hearing aid has hearing loss match up and adjustment of the hearing aid characteristics according to an individual patient. Digital hearing-aid device amplifies sound selectively by use of digital filters and the processed signal is transferred to the ear. Hearing-aid designers are continuously trying to minimize background sounds and noise with these additional directional microphones, adaptable noise reduction filters and uses of binaural hearing aid technologies to improve localization. Lots of studies have been already done to design digital filters for selective amplification. Most of the available hearing-aid designs have digital filter bank and fixed sub-band structure. Previous research aims at creating band decomposition, and the research is focused on using less complex algorithms for accomplishment of the decomposition of signals. The paper reviews available designs and reconfigurable digital filter banks to achieve the best fitting to audiogram.
