This concept provides a cost efficient manner of electricity billing. The present energy billing systems are discrete, inaccurate, costly and slow. The major drawback of traditional billing system is power and energy theft. This drawback is reduced by using an ingenious energy meter which is based on the concept “Pay first and then use it”. Prepaid mode of energy meter also reduces the human errors while taking readings to a large extent. The prepaid energy meter uses a recharge card which is available in various ranges. The recharge is done by utility through message to GSM module and the meter is charged with desire amount. The conventional postpaid mode is enriched with control at customer's premises from utility center. A Light Dependent Resistor circuit counts the amount of energy consumed and displays the remaining amount of energy on the LCD. So no additional replacement of existing meters is required. A relay system has been used which shut down or disconnect the energy meter and load through supply mains when the recharge amount is depleted. A buzzer is used as an alarm which starts before the recharge amount reaches minimum value.

As a result of series compensation, the sub-synchronous oscillation (SSO) causes a severe risk of torsional interactions (TI). Therefore, SSO becomes a serious risk factor in grid-integrated renewable energy systems. Numerous researchers have evaluated SSO instances in several types of asynchronous generators in power systems. In this paper, the categorization and the overview of the SSO phenomena have been vital for the different mechanisms, sophisticated systems, analytical techniques, and multiple reviews that have been propagated. This study provides SSO analysis for various types of renewable energy power plants. Finally, while dealing with conventional and new power systems, this study summarizes recent SSO-damping and alleviation techniques for practical perception and future perspectives.

Proposed work for protection of motor from over voltage(OV), under voltage (UV), over current (OC), under current (UC), over frequency (OF), under frequency (UF), single phasing, voltage asymmetry, current asymmetry, phase reversal etc. Such protection will help to protect motor from faulty conditions. The performance of system investigated through MATLAB / SIMULINK. Microcontroller used for programming of all types of abnormal conditions so that it will detect the faulty condition and protect motor from it. Micro-controller programmed with some threshold values and it will compare with actual loading condition, which will send a signal to breaker to open/close as per the condition. Condition may be faulty or normal operating, if it is faulty then open breaker otherwise remains closed.

The proposed system is combination of grid connected PV system battery backup system. In day time the irradiance is high, due to this generation of power is more. But in the night time irradiance is reduced, so power generation also reduces. To overcome this drawback a battery backup system is integrated with the conventional grid connected PV system. This increases exporting rate of the power units. PV array system is sectioned into three parts such as a grid tie inverter, a grid filter, battery backup system. This system gives simple, reliable, steady and appropriate model which helps to ease the understanding of grid-connected PV system. This paper elaborates MATLAB/Simulink model of grid-connected PV panel and Battery storage systems.

Welldesigned excitation systems provide reliability of operation, stability and fast transient response. Excitation systems provide and control the amount of DC current provided by field windings of the generator and this contains all the power controlling and protection components. To fulfill the power demands and desired output characteristics, the excitation system should be configured to match the power system to which the generator is attached. There are two primary aspects of the excitation mechanism: It generates DC voltage (and power) to allow the current through the generator's field windings and it offers a way of controlling the generator's terminal voltage to suit a specified setting point and to provide damping for oscillations in the power system. An aim of the paper is to analyze the two modern static excitation system Viz. ST1A and ST7B from the point of view of their relative performance. The simulation of these models performed in MATLAB SIMULINK environment by considering Single Machine Infinite Bus benchmark incorporated with a hydropower plant model.

The stability of the grid during periods of low grid activity is one of the most severe challenges. As a result, a new emphasis stability strategy is developed. This technique covers the doubly fed induction generator based power system with sub-synchronous oscillation (SSO) and presents a solution for uncertainty, damping demand, and voltage stability. In variable speed hydro systems, excessive compensation can occur at first; however, this can be avoided by employing a new safeguard uncertainty controlling strategy. This paper presents an innovative dampness optimization algorithm to damp SSO by tuning the rotor side converter. A novel momentum variable regulator approach is also presented to reduce maximum torque and speed variation in DFIG using power electronic converters to dampen the sub-synchronous oscillation. The simulation study shows that the SSO in DFIG based hydropower system can be minimized with the proposed approach while reducing the variations in maximum speed and torque.
