Simulation and evaluation of PV power generation for energy management system using SPICE

Abstract

Energy management system (EMS) using natural energy such as sunlight is expected to build a low-carbon society. In this paper, we report the modeling of the Si-bifacial photovoltaic (PV) module and the accuracy evaluation of simulation at Hokuriku region where is one of heavy snowing area in Japan. We develop the simulation model of PV power generation using simulation program with integrated circuit emphasis (SPICE). To simulate the generated energy accurately, the global solar radiation is used as the input and the model of the bifacial PV module is fit to actual measured value. The model of maximum power point tracking (MPPT) control module is constructed by Verilog-A language. We simulate and evaluate the generated energy in each season. The SPICE model with Verilog-A for EMS can be estimated the PV power generation within 10% of deviation at Hokuriku Region in sunlight day with the exception of winter.
