Electric Water Heater (EWH) is one of the most
power consuming devices in a house and it is very convenient
for demand response applications. However, demand
response potential of EWH is not utilized by the users. In
order to provide the greater participation of EWHs to
demand response, they should be controlled automatically,
not with human hand. Active control of the EWH in
accordance with the price information from the network is
recommended for this purpose. Active control (AC) is
performed via Smart Meter (SM) and Active Control Units
(ACU) in the house. While electricity prices are sent by the
smart grid to ACU via SM, the users introduce their comfort
temperature zone and demand response participation rate to
the ACU. Updated temperature set point for water heating is
determined by ACU using network information and the user
preferences. When electricity price is high, the temperature
set point is set to a lower value and when the electricity price
is low, temperature set point is adjusted a higher value
according to the user requests. In this study, active control of
the temperature set point is carried out on physical model of
EWH. Energy consumption quantity and cost are compared
for the cases where AC is implemented and AC is not
implemented. Active control of EWH provides decrease in
energy consumption costs for the user and to reduce the peak
loads in terms of grid, as well.

Current-Voltage (I-V) and Power-Voltage (P-V)
characteristic of Photovoltaics (PV) modules are important issues
in order to provide maximum power point (MPP) of PV. I-V and
P-V characters are related to the environment, which certainly
means that the efficiency of these cells affected by the
environmental factors like temperature, radiation, dust, etc.
Most recent trends in solar design use computer modeling to
connect solar lighting systems, solar heat and ventilation
considering weather data due to their effects on the solar cell
performance. This paper presents the modeling and simulation
of PV module using the MATLAB/ Simulink for calculating and
plotting the I-V and P-V characteristics of PV module. Datasheet
parameters of Mitsubishi PV-UD190MF5 PV module has been
used for simulation. Effects of irradiance, temperature and
connection types on the PV efficiency are investigated. The
output performance of the PV panels is evaluated under different
test conditions.
