Large number of transmission voltage level PV plants are integrated into the existing transmission networks. As PV penetrations on weak transmission links increases, its impact on power system stability also increases. Low frequency oscillations are produced due to this reason. The influence on low frequency oscillations vary, it can be positive or negative depending upon the location and sizes of large scale PV plants. The low frequency oscillation (LFO) changes as its location changes, but it is not possible to shift these plants to an ideal location where the influence of low frequency oscillations less. So a damping controller has to be designed in order to reduce the low frequency oscillations. The POD is based on minimax linear quadratic gaussian method. In order to illustrate damping performance of the designed controller, a test system prone to power system oscillations is used. The test system and the PV model are simulated and then connected to analyse the produced oscillations. Then for mitigating the oscillations, the damping controller is designed. For designing of minimax LQG controller, state space representation of the entire power system model is required. From that state space matrices, by following a step by step procedure of minimax LQG method, the controller matrix can be formulated. The POD can be used to eliminate the low frequency oscillations. Controller is also designed using LQG method and by comparing the damping of oscillations by these two methods, we can see that minimax LQG method gives better damping of oscillations.

The main objective of the power system is to provide good quality of power to the consumer. Continuous change in frequency by variation in load is a big challenge for generating unit to compensate it quickly as possible. Load Frequency Control (LFC) acts essential role to mitigate this problem by maintaining the frequency up to its desired level. PI and PID are conventional controllers can be used for LFC. Battery Energy Storage System (BESS) gives better results than conventional controllers. With the help of BES System voltage can be build up to, as many systems required. But if conventional controllers and BES System used together then more effective result can be achieved rather than their individual use for LFC. This paper presents a comparison of multi-area LFC with and without conventional controllers and conventional controllers in the presence of BES System. By using these both strategies together gives the best result as which system required.

Social acceptance is important for large scale implementation of new technologies such as renewable energy technology. Positive public opinion/participation is a must for adoption of technology such as solar energy technology and implementation of government policies. In this paper the public opinion of the people of three villages (Gajner, Kolayat and Nokha) on solar energy technology is discussed. The three villages are situated near Bikaner town of Rajasthan, India. These villages are in the proximity of number of solar power plants. The survey is based on “Qualitative and Quantitative” methodology to explore public opinion and impact of technology on their day to day life. The study concerned is about survey of 172 persons, who are residing near solar PV power plants in these villages. The questionnaire contains 14 questions to every person and answers have been obtained after interviewing them personally. This sample study shows that about 91.27% residents are in favour of establishment of new solar power plant near their agriculture fields and 91% respondents would like to install roof top solar panels for their domestic power needs. 89% respondents of these villages believed that this power plant provides electricity and job opportunities. However 7% opined that solar power plant is not beneficial for them.

Now days due to the ever increasing demand of electricity, laying of new transmission lines is needed tremendously. But due to cost and right of way concerns it is not that much easy so we can make use of already established double circuit line to their full capacity by combining these high voltage ac lines with dc. We can utilize the transmission line close to their thermal loading and superimposed power will not cause any instability. This paper shows the possibility of conversion of ac lines into combined alternating current direct current line rather than changing line conductor, line insulators also tower structures, there will be substantial increase in power transfer capacity. This concept is manifested using MATLAB/SIMULINK

Hybrid stand-alone power systems offer an achievable arrangement in remote and island zones where grid connection is not monetarily or in fact suitable. Nonetheless, the intermittent way of renewable energy sources and mismatch between the generated power and load demand are the principle challenge. In this way energy storage device is required to ensure efficient, reliable and secure power supply. An appropriate control for each generating unit and energy storage device is imperative. This paper proposes a DC linked hybrid solar wind energy system for stand-alone applications. Solar and wind energy are used as essential energy sources and battery unit is considered as a storage to take care of the load demand. Adaptive neuro fuzzy inference system is used to compute the panel voltage at which the maximum power can be tracked for solar system. It is likewise used to figure the maximum power created by nonlinear and irregular nature of solar and wind energy sources. A general power management strategy is intended for the proposed system to oversee power streams among the distinctive energy sources and charging and discharging of the battery in the system. A simulation model for the hybrid energy system has been created utilizing MATLAB/Simulink and tried for different irradiation, temperature and wind conditions.

The exponential growth of population has resulted a significant increase in power demand. Moreover the consumer area is vastly dispersed. Thus, the generation of electricity at the consumer side is gaining more popularity. The main problem associated with the generation of electricity at consumer side i.e. distributed generation is the failure of coordination between various protective devices employed in the system. Because after the integration of DG with the grid, the conventional radial distribution network is changed to interconnected mesh network. Therefore the existing protection system will not work satisfactorily in this case. This necessitates the modification of existing protection system or implementation of newer one. This paper recapitulates the impacts of DG on line losses, voltage profile, short circuit power levels of the network and presents a smart and adaptive methodology for protection of distribution network with distributed generation.

In this work a PV powered DC refrigerator was experimentally studied and exergic analysis was performed in both the refrigerator and PV panel. In this study the maximum exergic loss was observed in the PV panel which amounted to approximately to 86.23% loss. This was due to the thermal and electrical loses in the PV panel thus it is important to reduce the cell temperature to improve the performance of the PV panel. In the refrigeration side the experimentation was performed in a controlled environment chamber test facility at 25°C, 28°C, 31°C and 34°C to maintain consistency. A DC regulated power supply was used to power the refrigerator with the operating current and voltage. The operating current and voltage were obtained from the PVsyst software for a given solar irradiance and ambient temperature. The maximum exergic loss was observed in the compressor followed by the evaporator then the condenser and minimum exergy loss was observed in the expansion device. All the exergic loses in the refrigeration unit were directly proportional to the ambient temperature and minimum exergy loss was observed at 25°C.

In this paper, we report speed control of dc motor using android smart phone through Internet. Internet has become one of the irreplaceable tool for communication but in recent years it has gone a step ahead of controlling any machine which placed remotely. In the proposed system, the industrial machines like cranes, traction motors can be controlled remotely by just scrolling the widget in the android smart phone. This gives enough opportunities for physically challenged people to operate industrial machines more easily and safely. The proposed system is simple, cost effective and digital. The MATLAB and PROTEUS simulations confirmed the theoretical estimates of the performance of the proposed system.

Researches related to non-conventional energy sources have grown significantly in the present scenario. The electrical energy from the PV panel is considered as one of the most useful natural resources. This paper deals with the operation and control of a grid connected PV system with a nonlinear load. A utility grid connection is provided in order to replenish energy levels in case of power shortage from the renewable energy sources. Hysteresis Current Controller is employed for the inverter control. The proposed inverter control technique interfaces renewable energy sources and the AC bus of micro grid. It offers the possibility to inject power from the renewable sources and also improves the power quality in the same micro grid. Simulation results show the effectiveness of the proposed inverter control technique in improving the power quality of the system.

Depletion of commercial energy sources and many advantages of Renewable Energy Sources (RES), more research is emphasis on RES and its components. Generation by RES is generally distributed by using low voltage DC (LVDC) distribution. It is very essential to protect components of LVDC from fault and abnormal conditions. Switchgears/ Protection devices are used to isolate healthy part of electrical system from faulty network, by using various fault detection and control mechanism. Generally protection is given to the grid which integrates RES and existing grid provides power to load. At the occurrence of fault, faulty bus goes out of operation and source which is working in normal condition also disconnects from the load. So in order to maintain supply continuity, it is necessary to provide separate protection for each RES which acts as Distributed generation. The proposed scheme for protection of a LVDC Distribution system in a microgrid, automatically detects fault and isolates the faulty section. It integrates source of the faulty bus with another source and also cascade load at same time of integration. This helps in maintaining supply continuity to respective load and under utilization of RES/DG. To fulfill characteristics such as fast interrupting time and high short-circuit current withstanding capability, solid state/digital switches such as MOSFET, IGBT, etc can be used. The proposed said scheme is verified by MATLAB Simulation.
