Abstract: | Stand-alone hybrid energy systems are an enticing option for electrification in remote areas in several aspects such as grid extension difficulty, economic feasibility, and reliability. The use of existing micro-hydropower (MHP) with other renewable resources in rural areas has not been well studied. Moreover, it is challenging to use mathematical optimization algorithms for these kinds of real-world problems, so the derivative-free algorithm is highly sought. In this study, a methodology has been proposed to perform the optimal sizing, financial, and generation uncertainty analysis of Solar Photovoltaic (SPV) based on an MHP is proposed to handle the intermittent power output of the SPV. The analysis is performed in two cases: using storage and without storage. The optimal sizing is performed using the least present value cost and reliability constraint using different derivative-free algorithms. Additionally, the system need to be technically sound and ensure the frequency stability during load and source imbalance. In this study, the Syncronverter (SV) based on a micro hydropower System (MHPS) is proposed to handle the intermittent power output of Solar Photo-voltaic (SPV). The standalone microgrid is modeled in the MATLAB/Simulink environment. The power control form SV is performed using Power Angle Control (PAC) method. Several case studies are performed, and the simulation results show the dynamics of appropriate sharing of power for both the linear and nonlinear loads by the hybrid system. Both the frequency and Total Harmonic Distortion (THD) of load voltage kept within the standard limits. Moreover, the dynamic response of voltage, power, and frequency of the system due to the induction motor load has also been studied. |
