What is it about?
At the edge of the crisis of conventional sources of energy (example oil, gas, and coal), photovoltaic (PV) cells are often stated as being the most reliable element among the renewable energy sources. However, in recent years PV cells are changing from small isolated systems to large grid-connected power stations. In this new scenario, PV cells will become possible solution to power crisis and its application as additional energy sources in power system based on reliability model will become of utmost importance. This paper presents an effective simulation method of reliability index, load carrying capability (LCC), to analyze the future effect of additional PV cells generator on Bangladesh Power System (BPS). For this reason, generator model, PV cells reliability model and load model are used to analyze the pertinent available generator data and load data of National Load Dispatch Center (NLDC) of BPS for the year of 2012. Furthermore, the effect of different uncertainty of the additional PV cells generation of 500 MW analyzed in the test simulated MATLAB environment is depicted graphically at the end.

Why is it important?
We present a simulation-based reliability analysis focusing on the load carrying capability (LCC) of photovoltaic (PV) cells integrated into the Bangladesh Power System (BPS). This is important as Bangladesh transitions away from conventional fossil fuel sources towards renewable energy, with PV technology evolving from small-scale isolated systems to large grid-connected installations. Two significant contributions of this study are: a) the development of a comprehensive reliability model incorporating generator, PV cells, and load data from the National Load Dispatch Center (NLDC) to assess the impact of a 500 MW PV generation addition, and b) the quantitative evaluation of uncertainties inherent to PV generation, providing critical insights for planning and enhancing power system reliability. These findings are timely for policymakers and engineers working to design resilient and sustainable energy infrastructures in rapidly developing regions.
Perspectives
I hope this article helps readers appreciate that integrating renewable energy into power systems is not only about adding clean sources but also about ensuring those sources reliably meet demand under real-world uncertainties. While PV cells offer promising solutions to energy crises, understanding their reliability and impact on system stability is crucial for effective planning. Personally, I find it exciting that this research blends advanced simulation techniques with practical data from Bangladesh’s power grid, highlighting how engineering and policy must work hand-in-hand to build a sustainable energy future. More than anything, I hope readers find this study thought-provoking and a call to action for continued innovation in renewable energy integration.
