Global weather concerns have diverted the researchers to look out for clean and green energy sources. The wind power has been utilized since old days for applications such as pumping water, grain grinding mills, driving ships, etc. However, due to its uneven nature, wind energy has never been a choice of power engineers. With the inherent variability of wind due to fluctuating weather conditions, wind speed prediction techniques play a vital role in determining the feasibility of esteemed wind power projects. Modern weather forecasting involves a combination of analyzed data, computer models, knowledge of trends and patterns. In this paper various short-term statistical wind speed forecasting techniques have been analyzed and focused upon.

In this paper a new approach is taken to solve the stability problem in the power system with the help of Flexible AC Transmission System (FACTS) devices and Tilt Integral Derivative (TID) controller. The FACTS devices can enhance the power system capability of transmission. A number of FACTS devices are working in the power system. Among these FACTS devices, Static VAR Compensator (SVC) is a shunt connected FACTS device which can be used effectively in Voltage Control mode. In the MATLAB power system model, SVC is operating with a PI controller, which has simple functioning and is cheaper in operation but has poor performance with non-linear characteristics. So to overcome this problem the controller is designed as a combination of both TID controller and Fuzzy Logic controller. TID controller has a tilted component, which replaces the proportional component in the PID controller. In this paper the suggested controller has been tested on a 2 machine 3 bus power system using MATLAB/SIMULINK software. The simulation consumes lesser run time and there are fewer oscillations in the system with the hybrid TID and Fuzzy Logic controller.

Dust on photovoltaic modules reduces its efficiency by decreasing its transmittance hence the effective solar insolation reaching it is reduced. Studies have shown dust or minute particle is affected by tilt angle of solar collector, exposure period, site climate conditions, wind movement and dust properties. Previous authors have calculated loss in terms of optical loss that is reduction in transmittance but paper calculates the loss in terms of kWh which was not done till now.

This paper presents a single stage solar photovoltaic (PV) grid interfaced power generating system using two-level 12-pulse double bridge voltage source converter (VSC) with improved sinusoidal signal integrator PLL (SSI-PLL) based control algorithm for large capacity plants with improved power quality. The maximum power is tracked with modified perturbation and observation (P&O) maximum power point tracking (MPPT) method and the maximum power obtained is transferred to the grid. Multipulse VSC results in reduction of grid current and grid voltage total harmonic distortion (THD) which is in accordance to the IEEE 519 standard without performing high frequency switching control. Simulated results have validated the design and control algorithm of the proposed system configuration under varying conditions.

The Phasor Measurement Units (PMU) installations worldwide along with the advancements in computing and communications enabled the time tagged phasor measurements of voltages and currents. These real time phasor measurements have become the backbone of wide-area monitoring, protection, and control for various applications in power systems. This paper highlights the monitoring of voltages and phase angles across different nodes that provides very useful information indicating the system state and its proximity to stability limit. The most crucial task is placement of PMUs at minimum number of buses for complete observability. Recursive spanning tree algorithm of PSAT is applied to find out the minimal placement locations for observability of all buses. The Thevenin's equivalent parameters have been obtained from the measured and estimated voltages at the load buses and impedance matrix Zbus. The parameters obtained are used to find the voltage stability boundary. Results on IEEE-14 bus system and IEEE-30 bus system are presented to illustrate the proposed approach.

Power Electronic equipment that converts a DC power into AC power at required voltage and frequency level is known as Inverter. Voltage Source inverters produce an output voltage or current with levels either zero to positive voltage or zero to negative voltage that means two levels. These bi-level inverters are powered by different type of gating signals like square, quasi - square and sinusoidal Pulse width modulated signals. Different gating signals result in different harmonic levels in the output signal. In this paper, a hardware prototype of a single phase inverter using MOSFETs as the power switches has been developed. The MOSFETs are driven by square and quasi-square gating signals. These gating signals have been generated by designing the driver circuit using a MOSFET driver IC. In order to maintain the voltage level, the conduction time interval of MOSFETs has been maintained by controlling the pulse width of the gating pulses. Performance of the inverter has been studied for RL load. Simulation has been done in SIMULINK, results of simulation and experimental model has been compared on the basis of various parameters like output voltage, load current and THD levels.

In this paper a charge pump based buck converter is proposed and its suitability for constant load voltage applications is investigated. Steady-state time-domain analysis is established and then proved that this converter gives bucking feature like conventional buck converter voltage transformation. State-space analysis, discrete-time models are formulated and then discrete-time transfer functions required for digital controller design are obtained. A single-loop digital direct duty ratio controller is designed. A 42 to 28 V, 100 W prototype converter is used to predetermine the proposed converter performance in simulation environment. Simulation studies demonstrated the bucking as well as load voltage regulation feature. Analytical investigations and simulations are validated through experimental measurement.

This paper proposes a novel H-bridge based hybrid multilevel inverter consists of small number of switching devices and output of H-bridge multilevel by switching the solar PV voltage sources in series and parallel. The proposed H-bridge multilevel inverter reduces number of switching devices which reduces the power consumption and size of the gate driver circuits. The proposed inverter gives more number of output voltages which reduces total harmonic distortion of the output voltage waveform. The hybrid modulation method is used to control H-bridge multilevel inverter. The proposed inverter is validated through simulation results are validated by using MATLAB/SIMULINK.
