Dual-mode MPPT Algorithm of Natural Gas Differential Pressure Power Generation System

Abstract

The natural gas differential pressure power generation system can convert the pressure energy into electric energy in the process of natural gas pressure regulation, which is of great significance for developing clean energy. To improve the energy utilization of the differential pressure power generation system, a dual-mode maximum power point tracking (MPPT) algorithm is proposed. The algorithm has good tracking accuracy and stability, combing the optimal characteristic ratio method with the variable step-size climbing method. The simulation results show that the proposed algorithm can quickly track the optimal working point under different working conditions, which verifies its effectiveness and applicability.
