Different Strategies for Power Quality Improvement in Off-Grid Renewable Energy Based Power System

The increasing trend in integrating intermittent renewable energy sources into off-grid power system presents major challenges from the viewpoints of reliable operation and control. In this paper, the major problems and challenges in off-grid power system control are discussed, and a review of control strategies and trends is presented. A general overview of the main control is also included. The paper classifies power quality improvement strategies into three levels: primary, secondary, and tertiary, where primary and secondary levels are associated with the operation of the off-grid power system itself, and tertiary level pertains to the coordinated operation of the power system. Each control level is discussed in detail in view of the relevant existing technical literature.

Different Technologies and Components of Renewable Energy Sources based Power System: A Review

Variability and intermittency are some of the main features that characterize renewable energy sources. Intermittency usually includes both predictable and unpredictable variations. The many drawbacks of intermittency of renewable sources can be overcome by considering some special design considerations. Integrating more than one renewable energy source and including backup sources and storage systems are among the few measures to overcome these drawbacks. These additional design considerations usually increase the overall cost of the renewable system.

Furthermore, the presence of more than one energy supply/storage system requires the control of energy flow among the various sources. Therefore, optimizing the size of the components and adopting an energy management strategy are essential to decreasing the cost of the system and limiting its negative effects. The energy management strategy is commonly integrated with optimization to ensure the continuity of load supply and to decrease the cost of energy production. Therefore, energy management is a term that collects all the systematic procedures to control and minimize the quantity and the cost of energy used to provide a certain application with its requirements.

The energy management strategy usually depends on the type of energy system and its components. Various approaches and techniques have been used to develop a successful energy management strategy. In this paper, a comprehensive review of the different combinations and approaches proposed and used by authors of many papers are conducted. These approaches include both the standalone hybrid renewable energy systems and the grid-connected hybrid renewable systems. The selected papers in this review cover the various configurations of the hybrid renewable energy systems for electric power generation only.

Power Quality Improvement in Solar-Wind based Power System using BESS

As solar photovoltaic and wind based power generation becomes more commonplace, the inherent intermittency of the solar and wind resource poses one of the great challenges to those who would design and implement the next generation smart grid. Speci?cally, grid-tied solar power generation is a distributed resource whose output can change extremely rapidly, resulting in many issues for the distribution system operator with a large quantity of installed photovoltaic devices. Battery energy storage systems are increasingly being used to help integrate solar and wind power into the grid.

These systems are capable of absorbing and delivering both real and reactive power with sub-second response times. With these capabilities, battery energy storage systems can mitigate such issues with solar-wind power generation as ramp rate, frequency, and voltage issues. Beyond these applications focusing on system stability, energy storage control systems can also be integrated with energy markets to make the solar and wind resource more economical. Providing a high-level introduction to this application area, this paper presents an overview of the challenges of integrating solar and wind power to the electricity distribution system.In this paper a solar-wind based power system model is made.

To smoothen the intermittency of the solar and wind resources a battery energy storage system (BESS) is employed. The battery energy storage system stores the energy when excess power is available and releases the stored energy when demand is higher than the supply. A PI controller based control scheme is implemented for this purpose and an MPPT is used for wind turbine to extract the maximum power from the wind resource.The validity of the control scheme is checked through the MATLAB simulation of the solar-wind based power system.

Combined Effect of Marble Dust and Steel Fiber on the Mechanical Properties of High Strength Concretes

Present day construction cost is at its height with using basic materials like cement, coarse aggregates and fine aggregates. Leaving waste materials to nature specifically can bring about environmental issues. Therefore, reuse of waste materials has been emphasized. Industries produce lots of waste materials, which might be helpful in partial replacement of basic materials due to their composition and it can be proved economical.

The concrete industry is always searching for supplementary material with the target of decreasing the solid waste disposal issue. As we know concrete is weak in tension so, to overcome this, steel fibers has been used. There are few reuse and recycling solutions for this industrial by-product, both in experimental phase and have useful applications. These mechanical wastes are dumped in the close-by areas and natural fruitfulness of the soil is ruined.

The physical, mechanical & chemical properties of wastes are discussed. In this study, marble powder has replaced sand, the whole research is carried out on M60 grade concrete with partly replacing sand by 0%, 15%, 30%, 45%, and 60% of marble dust, with the addition of steel fibers at ratio 0.8% by volume so as to get greatest compressive strength, flexural strength and furthermore split tensile strength.

Based upon the feasibility interpretation it is observed that replacing up to 45% marble powder and 0.8% of steel fibers in concrete is appropriate in conformance with the requirement. The compressive strength and the spilt tensile increased up to 15% replacement, after that they started decreasing.

A Review Study on Preventing and Detecting Technique of Black Hole Attack in MANET

There are basically two types of black hole attack i.e. internal black hole and External black hole attack. Black hole is a malicious node that wrongly replies for some route requests without having active route to particular destination and drop all the getting packets. If these malicious nodes work jointly as a collection then the damage will be very risky. This type of attack is called cooperative black hole attack. Black hole attack is a type of active attack. Black hole attack can arise when the malicious node on the path attack the data transfer and purposely drop, delay or change the data transfer passing through it. Black hole node treats itself as a trusted node.

This is review study on Black hole node send false routing information, claim that it has a best route and cause additional good nodes to route data packets through the black hole node.

Techno-Economic and Environmental Analysis of Wind-Diesel Power System

This paper discusses the economic analysis and environmental impacts of integrating a photovoltaic (PV) array into diesel-electric power systems for remote villages. MATLAB Simulink is used to match the load with the demand and apportion the electrical production between the PV and diesel-electric generator. The economic part of the model calculates the fuel consumed, the kilo watt hours obtained per gallon of fuel supplied, and the total cost of fuel. The environmental part of the model calculates the particulate matter (PM), NOx and CO2 emitted to the atmosphere.

Simulations were performed for three cases: 1) diesel only; 2) diesel-battery; and 3) PV with diesel-battery using a one-year time period. The simulation results were utilized to calculate the energy payback, the simple payback time for the PV module, and the avoided costs of CO2, NOx, and PM
