The Introduction of the Special Issue

SOLAR photovoltaic (PV) panels are used to harness the solar energy and convert solar energy into electricity. The PV installations can produce power in the range of a few Watts to a few hundred Mega Watts. This enables the use of the PV panels in systems having varied power demands. Additionally, the PV panels can also be placed easily on roof-tops of houses, offices, or buildings due to various factors including easy installation and low maintenance. These PV panels do not require additional space within the buildings.

Conventionally, for extracting of the maximum available renewable power from PV panels, these must be operated at maximum power point (MPP). The MPP depends on various conditions such as properties of PV panels, environmental factors such as solar insolation, temperature, etc. An MPP tracking (MPPT) controller uses a DC-DC converter to match the impedance seen by PV panels to operate at MPP. Conventionally, various types of hill climbing MPPT controllers, are used for achieving maximum power from PV panels. The PV array operating point is changed with help of MPPT algorithm by changing the DC-DC converter duty cycle . General system comprises a PV array, an MPPT controller, a pulse width modulation (PWM) generator, a DC-DC boost converter, and a load. The PV array is connected to the DC-DC boost converter with the MPPT controller and then to the load. The MPPT controller uses sensed output voltage of the PV array, i.e. V_pv, and the output current i.e. I_pv to track the MPP. Based on an MPPT algorithm, the MPPT controller generates required duty for the DC-DC boost converter. Based on the pulse width of the DC-DC boost converter, the input PV voltage (V_pv) reaches maximum power point voltage i.e. V_mpp and corresponding output voltage (V_O) appears across the load. Further, the voltage V_pv and the current I_pv are sensed by using sensors and scaled as per controller ADC (Analog-To-Digital Converter) resolution or noise floor. The voltage, V_pv can be measured using simple potential divider arrangement for non-isolated measurement. Generally, Hall Effect sensors or shunt resistor sensors are the most commonly used transducers for sensing the current, I_pv. The Hall Effect sensor measures I_pv by measuring magnetic field created by the same. However, the Hall Effect sensors are very sensitive to external magnetic fields and hence, are easily affected due to external or stray magnetic field . Hence, in this special issue, the problem related to solar MPPT techniques are welcomed for submission.
