Photovoltaic (PV) arrays have become very popular in on-grid and
off-grid systems due to their simplicity, low emissions and low
levelised costs of electricity.
PV arrays are connected to grid systems via power electric
converters and typically have embedded maximum power point tracking
algorithms.
Describe how a PV system with maximum power point tracking may
be modelled in a dynamic simulation package.
Good old Florida! As an alum of UCF, you also plan to use an
off-grid power system. While you absolutely adore four-wheel drive,
you bought a plug-in hybrid car, for cost efficiency. Estimate the
number of excess solar panels you would need to add to your
off-grid power system in order to keep your car charged up without
ever burning a drop of gasoline.
Define a 3 phase short circuit and a line to ground
faults in a PV system. How it affect the load and how it can be
eliminated. Also make analysis on how it affect active and reactive
power and the efficiency of the system.
Please show work by hand thank you
2 alternatives for an off-grid energy system are being compared
by a company building a house in New Mexico (From Providers A and
B). Alternative A is a solar energy system that has a life of 8
years, the first cost of $18,000, annual energy cost savings (can
be treated as revenue in this cash flow) of $2600, and a salvage
value after 8 years of $9000. Alternative B is a wind energy...
To meet the tolerance required for a surveying project, it is
necessary to use a total station. An obstacle makes it impossible
to obtain a direct line of sight. Explain one technique that you
would use to establish the line of sight past the obstacle. Use a
sketch if necessary (0.5 marks)

Define each of the following theories accompanied by equations.
Hypothetical examples are required.
a. Interest rate parity.
b. Expectations theory of forward rates.
c. Purchasing power parity.
d. International capital market equilibrium (relationship of
real and nominal interest rates in different countries).
Discuss the basic components of a simple cost system. Define an
ABC cost system. What are the advantages of an ABC system versus a
simple cost system? Are there disadvantages to an ABC system?
