Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

8. Ohm’s Law
Ohm’s law states that the voltage or potential
difference between two points is directly
proportional to the current
or electricity passing through the resistance,
and directly proportional to the resistance of
the circuit. The formula for Ohm’s law is
V=IR. This relationship between current,
voltage, and relationship was discovered by
German scientist Georg Simon Ohm.
10. Most basic components of electricity are
voltage, current, and resistance. Ohm’s
law shows a simple relation between these
three quantities. Ohm’s law states that
the current through a conductor between
two points is directly proportional to the
voltage across the two points.
11. Ohm’s Law Formula
Voltage= Current× Resistance
V= I×R
V= voltage, I= current and R= resistance
The SI unit of resistance is ohms and is
denoted by Ω
This law is one of the most basic laws of
electricity. It helps to calculate
the power, efficiency, current, voltage,
and resistance of an element of an
electrical circuit.
12. Limitations of Ohm’s Law
Ohm’s law is not applicable to unilateral
networks. Unilateral networks allow the
current to flow in one direction. Such types of
network consist elements like
a diode, transistor, etc.
Ohm’s law is also not applicable to non –
linear elements. Non-linear elements are
those which do not have current exactly
proportional to the applied voltage that
means the resistance value of those elements
changes for different values of voltage and
current. Examples of non – linear elements
are the thyristor.
13. Uses of Ohm’s Law
The basic quantities of electricity are the
current, voltage and resistance. Ohm’s Law
establishes a simple equation between the
three quantities, serving as the most basic
law of electricity.
Ohm’s law helps in calculating the power,
efficiency and the impedance of any element
of the electrical circuit.
It helps in determining the voltage, current or
resistance of a linear circuit when either of
the two quantities is known.
14. Kirchhoff’s First Law – The
Current Law, (KCL)
Kirchhoff’s Current Law or KCL, states
that the “total current or charge entering a
junction or node is exactly equal to the
charge leaving the node as it has no other
place to go except to leave, as no charge is
lost within the node“. In other words the
algebraic sum of ALL the currents entering
and leaving a node must be equal to zero,
I(exiting) + I(entering) = 0. This idea by Kirchhoff
is commonly known as the Conservation
of Charge.
15. We can use Kirchhoff’s current law
when analyzing parallel circuits.
16. Kirchhoff’s Second Law – The
Voltage Law, (KVL)
Kirchhoff’s Voltage Law or KVL, states
that “in any closed loop network, the
total voltage around the loop is equal to
the sum of all the voltage drops within
the same loop” which is also equal to
zero. In other words the algebraic sum
of all voltages within the loop must be
equal to zero. This idea by Kirchhoff is
known as the Conservation of Energy.
17. Starting at any point in the loop continue
in the same direction noting the direction
of all the voltage drops, either positive or
negative, and returning back to the same
starting point. It is important to maintain
the same direction either clockwise or
anti-clockwise or the final voltage sum will
not be equal to zero. We can use
Kirchhoff’s voltage law when analyzing
series circuits.
18. Common circuit theory terms
Circuit – a circuit is a closed loop conducting path in which
an electrical current flows.
Path – a single line of connecting elements or sources.
Node – a node is a junction, connection or terminal within a
circuit were two or more circuit elements are connected or
joined together giving a connection point between two or
more branches. A node is indicated by a dot.
Branch – a branch is a single or group of components such
as resistors or a source which are connected between two
nodes.
Loop – a loop is a simple closed path in a circuit in which no
circuit element or node is encountered more than once.
Mesh – a mesh is a single closed loop series path that does
not contain any other paths. There are no loops inside a
mesh.
