A Case Study for Optimum Sizing and Selection of Components in HRERs based Power Sysetm

The demand of electricity in rural India is increased two fold in the last decade and this demand has been met by the electricity grid extension so far. But the cost of extension of grid is very high and also depends upon land location, distance to be covered and more importantly size of the load. The recent researches show that adding the renewable energy resources to the system at the load centre makes the system less costly and environment friendly. 

The different configurations are compared and the selection of optimum configuration is based on the least value of cost of energy (COE) and net present cost (NPC) along with the highest value of renewable fraction (RF) and lowest harmful emissions (CO2) using HOMER (Hybrid Optimization Model for Electric Renewables) software is presented. A village location, Kotali Charkan (32-° 37' 0" North, 74-° 50' 0" East) in Jammu and Kashmir state of India is chosen for the system under the study, the hydro, solar and wind resources are available almost throughout the year on the selected village location.

Load Frequency Control in Three Area Power System using Fuzzy Logic Controller

In interconnected power system load frequency control has been used extensively. This study presents an application of a fuzzy gain scheduled proportional and integral (FGPI) controller for load-frequency control of a three-area electrical interconnected power system. The main aim is to design a FGPI controller that can ensure good performance. The paper present analysis on dynamic performance of Load Frequency Control (LFC) of three area interconnected thermal non-reheat power system by the use of Fuzzy Intelligence. 

The fuzzy rules are developed to ensure there is minimum frequency deviation occur when load is changed. The proposed controller limits the frequency deviations effectively as compared to conventional controller. The results has been verified by using MATLAB/Simulink software.

Modelling and Simulation of Grid-Connected Solar-Hydro based Hybrid Power System

In this paper DC linked, grid connected solar/hydro hybrid system is modelled and simulated. A control scheme is developed for solar and hydro system for variable solar irradiance and variable load. Synchronous generator based hydro system is used to feed bulk of the power and whenever solar irradiance is available solar system along with hydro system and grid supply to the load. The performance analysis of the proposed HES and its power management strategy has been done using the simulink toolboxes of MATLAB software. 

The proposed system consists PV system hydro system, battery and grid. In some remote/rural areas, it is very difficult to satisfy the demand of electrical power throughout the year with the power grid. In such areas, the power requirement can be fulfilled by renewable energy system such as hydro or PV system. Either the hydro system or PV system is not capable of supplying power requirement throughout the year as both systems are intermittent. 

Hence, the judicious combination of hydro and PV system has been modeled for electrification. The power management strategy is modeled to manage the power flow of the energy systems to fulfill the load demand. The presented results clearly show that the proposed HES and its control strategy are suitable for implementation in remote/rural areas.

Modelling and Analysis of Grid Connected PV System under Different Penetration Level of PV

In the last two decades there is very sharp rise in the power generation from the solar system. This is due to the increasing solar cell efficiency, decreasing PV system costs, increasing government support, and many other factors collectively help in reduce the barriers of growth for PV systems to expand their participation to the total world energy sector. The drawbacks of the inverters which are currently used in grid connected PV system are well known. As the penetration of PV system is increasing day by day this problem is becoming more significant. 

This paper provide a solution in the control of inverter by regulating the active power and reactive power. The proposed control scheme helps in providing grid support by PV system as well as reducing the harmonics contents in the power hence improving power quality. The design, modeling, and analysis of a grid-tied PV system was performed in the MATLAB software simulation environment. Results indicate that in the presence of grid disturbances the proposed inverter can react dynamically to help restore the power system back to its normal state. A harmonic analysis was also performed indicating the inverter under study met the applicable power quality standards for distributed energy resources.

Power Management in Grid Isolated Hybrid Power System Incorporating RERs and BESS

The battery energy storage system (BESS) is one of the most commonly used method for smoothing the wind or solar power generation fluctuations. Such BESS based hybrid power systems require a suitable control strategy that can effectively regulate power output levels and battery state of charge (SOC). This paper presents the results of a wind/photovoltaic (PV)/BESS hybrid power system simulation analysis undertaken to improve the smoothing performance of wind/PV/BESS hybrid power generation and the effectiveness of battery SOC control. 

A smoothing control method for reducing wind/PV hybrid output power fluctuations and regulating battery SOC under the typical conditions is proposed. The effectiveness of these methods was verified using MATLAB/SIMULINK software.

Modelling and Control of Wind / PV / Battery / Fuelcell based Hybrid Power System

In this paper, a hybrid power system comprising wind and solar based renewable energy sources (RERs) is proposed. As these RERs are intermittent and random in nature, so a backup source is needed for smoothening the fluctuations in RERs output power. Fuel cell based energy storage system (ESS) along with battery energy storage (BESS) is proposed for this purpose. Both the energy sources are controlled so as to deliver energy at optimum efficiency. 

A separate controller is used to achieve maximum power tracking for both PV and wind resources for delivering maximum available power from these sources. PMSG based wind energy conversion system is used to extract energy from the wind. The energy from the solar, wind and fuel cell based power system is converted in to Ac form by using inverter. This power from point of common coupling supplies the load, while the excess power feeds the water electrolyzer used to generate hydrogen for supplying the fuel cells (FC). 

A management system is designed to manage the power flow between the system components in order to satisfy the load requirements throughout the entire operation. The study defines the power generated by the wind and PV systems is not predictable so BESS is used to smooth the large power variations and the generated hydrogen used and stored in tanks and the power generated by the fuel cells to supply the small deficiency in the load demand. Simulation results is obtained from MATLAB/Simulink software, proved the accuracy of the proposed system. Also, a complete description of the management system is presented.

The Behavior of the Television Audience by TV Rating with Social Networks

This examination looks at the connection between online networking webpage Facebook and TV ratings drawing from group of on looker's variables of incorporation model of gathering of people conduct. In view of setting of Taiwan broadcasting company programs, this examination gathered measures for Facebook shares, likes, remarks, posts for three classifications of network shows and Nielsen ratings over a time of 11weeks, bringing about the span of test in excess of 130 perceptions. This examination connected different relapse models and verified that the key online networking measures associate with TV ratings. 

Generally, TV appears with higher number of posts and engagement are probably going to identify with higher ratings, extraordinary in dramatization appears. Along these lines, this examination built the TV expectation models with measures for Facebook through SVR. The outcomes proposed that expectation models are a decent anticipating of which MAPE was between 10% - 20%, even fewer than 10%. This suggests TV system ought to be roused to put resources into web-based social networking and connect with their group of onlookers and examiners can utilize web-based social networking as an instrument of exact estimating.
