An Enemy to Friend Optimization Based Dc To Dc Converter for Building Integrated Photovoltaic (BIPV) System

building electrification
The Photovoltaic (PV) systems are mainly implemented to convert the solar irradiance into electrical energy. The PV modules used in Building Integrated PV (BIPV) is installed at separate orientations and angles. In the traditional systems, the performance of the PV modules are easily affected due to the mismatch of electrical parameters. Also, its power configurations are highly difficult, which leads to reduced reliability and energy efficiency. Thus, this paper intends to introduce a new DC-DC converter by implementing a novel Enemy to Friend (E2F) algorithm. Initially, the solar irradiance obtained by the solar panel is converted into DC by using the Maximum Power Point Tracking (MPPT). In which, the Pulse Width Modulation (PWM) is generated based on the optimization process, for this purpose, an E2F algorithm is implemented. In this technique, the enemy who has the minimum anger (i.e. the duty cycle which has the minimum value) is selected, then make it as a friend. The output power obtained after implementing the DC-DC converter is given as the input for inverter. Here, the Indirect Sliding Mode Control (ISMC) is utilized for controlling the power system. Finally, the output of inverter is either connected to grid or load. In simulation, the efficiency of the proposed optimization based controlling strategy is evaluated and analyzed by using the measure of DC-DC converter output and inverter output at varying temperature.
