This paper has proposed a new switching scheme for controlling dc-dc boost converter circuits. The is represented as hybrid system with three modes of operation. among these governed by the adjustable reference voltage and current which are calculated an energy balance principle. been applied to realistic circuit modeled various parasitic components. All specifications related ripple voltage, line load regulation shown be achievable relating them surfaces, namely current. state trajectories...
A stochastic procedure is described for producing probabilistic forecasts of monthly peak system demands up to three years ahead. The based on well-known concepts prediction theory stationary time series, which are developed further predict those types nonstationary series that can be reduced a by finite linear transformation. yields technique forecasting the evolving, and seasonal power demands.
This paper has proposed a new energy based switching scheme for controlling DC-DC buck converter circuits and analysed its stability. There are three modes of operations, the among these depends on reference voltage inductor current. The current is calculated by principle balance. designed to ensure that ripple as well average value output remain approximately constant in response line load disturbances. phase plane analysis sensitivity matrix show control free from chaos fact super-stable orbit.
This paper explores a technique to obtain constant output DC voltage from DC-DC power converter. The proposed control law overcomes instabilities arising in boost converters switched according voltage-based sliding surface. has been achieved by combining this switching surface with current-based one and selecting the appropriate given situation. Further ripples are controlled principle of energy balance. Whenever stored capacitor goes below threshold value, additional is drawn source...
Escalation in requirement of involvement solar energy the total generated power INDIA has made it mandatory to focus on flaws that still hinder path large scale inclusion energy. Thus this paper, enhance performance PV panels we firstly analyze various sort faults prevailing module related bypass and blocking diodes under partially shaded uniform condition.The hot spot occur due partial shading not only affect generation system but also causes multipeak point characteristics. The...
This paper has proposed a new switching scheme for controlling DC-DC boost converter circuits and presented the stability analysis by using method of multiple Lyapunov functions. The is modeled to operate in three modes operations. among these depends on capacitor output voltage inductor peak current. current calculated from basic principle energy balance. Whatever lost load, same amount be gained inductor. minimum load resistance also determine maximum transfer load. this analyzed phase...
The present work considers the task of forecasting GHI for 1-11h ahead forecast horizon from previous time-series data. Dealing with non-stationary and non-linear time series is a challenging vital part forecasting. This paper aims to GHI, comparing performance two decomposition techniques, i.e., EMD EEMD. These techniques divide original into set orthogonal series, which are termed as Intrinsic Mode Functions (IMFs). Further, problem converted supervised learning (input-output problem). A...

UHS (ultra high speed) refers to operating times of less than 5 ms on 50 Hz power systems. Three distinct types relaying realization in distance protection via advanced-generation digital signal processing, possible with cheap and readily available VLSI chips, are considered. Type I is the correlator detector: II III spectrum cepstrum analyzers, respectively. The performance these detectors evaluated respect varying system configurations that complicate post fault signals. Microprocessor...

This paper contains a detailed analysis of the stability limit cycle in steady state for DC-DC converter circuits using energy based control. The existence stable cycles boost is analyzed with Poincare mapping. Boost has always cycle, this proven analytically which could be done because control method leads to elegant, almost natural, working modes. system simulated, and results are verified.
Multi-pair two-way half-duplex massive multiple-input multiple-output (mMIMO) relaying with multiple user-pairs is being actively explored. Most of the existing mMIMO investigations consider either spatially correlated Rayleigh fading or uncorrelated Rician channel and also ignore impact phase shifts in line-of-sight (LoS) component due to change user location hardware effects. We a multi-pair amplify-and-forward relay system along shifts. derive asymptotic spectral efficiency expressions...
The need for solar photovoltaic (PV) power forecasting arises due to rapid fluctuations in PV output.
