    Integration of renewable energy sources into existing grid influence the stability of the power system. This article introduces the application of cascade controller in hybrid power system which enhance the frequency stability during power perturbations of the load and generation. For this study, a thermal power unit is considered with integration of a microgrid consist of regular diesel generator, renewable power generating units, energy storage and other power managing devices. Proportional-integral and proportional-integral-derivative (PI-PID) cascade controller is provided for this hybrid power system to reduce the frequency oscillations during system uncertainties. The optimal values of the PI-PID controller are achieved by using water evaporation optimization (WEO) algorithm with fast convergence rate. Investigations are carried out in different scenarios of the IM and results are compared with the PID controller to showcase the advantages of the cascade controller for frequency regulation. Simulations are carried out in MATLAB-SIMULINK® software environment.

    Fire mishaps are common nowadays, and at times it has become very challenging for firefighters to save personage entities. It became hard for a human being too constant supervision during accidental fire situations. Consequently, in such cases, a firefighting robot is handpicked. Particular robots are most fruitful in industries where the odds of unintentional fires are severe. Moreover, the initiated vehicle can recognize the existence of fire and extinguish it involuntarily by pumping out water. Temperature sensors and smoke sensors are used for the detection of fire. It contains a motor-driver module that controls the gesture of the robot. A relay circuit is handed down to direct the pump, and it automatically sprinkles water when the fire is noticed. The proposed robot also has an LCD that displays the temperature, smoke, and fire rate.

    Inverters have many Technological improvements in their maximum power handling capabilities by using renewable energy sources. Multilevel inverters give effective and efficient interface for renewable energy sources and perform Transformer-less operation and increase the power quantity and quality of voltage of the PV system. In this paper, the benefits of H-bridge inverters including the total harmonic distortions are discussed. This paper has primarily focused on Sinusoidal PWM and worked on the carrier based phase disposition techniques. The performances of modulation schemes are compared. Simulations were done using MATLAB Simulink for the given PWM techniques.
