“…A new type of physical system was developed and implemented in the Power System Stability Laboratory (PSSL) of Sofia University of Technology to evaluate the control performance of the NG (Stanev et al, 2018). An AC/DCNG was established in Universidad del Valle as part of MG (Franco-Mejia et al, 2017). And an ETAP model is established to compare with the field operation (Shafik et al, 2020).…”

As an emerging energy management technology, the DC nano-grid coordinates renewable energy sources output through demand-side management which would provide more options and flexibility for the dispatch of smart buildings and communities with high reliability and efficiency. In this context, this article has analyzed the structure and components of the DC nano-grid. The role and components in DC nano-grid are reviewed in this article. Then the crucial control technologies for the DC nano-grid in recent years are investigated from two aspects: local control and coordinated control, which contains control schemes such as voltage/current control technology, power-sharing technology and cooperative control technology. Different control strategies at various levels are compared and their application scenarios, advantages and disadvantages are also analyzed. The current research progress and challenges are summarized at the end of this article.

“…The microgrid is a new paradigm in the energy sector, which integrates parts such as renewable and/or non-renewable energy generation, energy storage, loads, power electronics, control, protection, and communications [1]. As part of the renewable generations, the PV generator consists of photovoltaic panels and a switching power converter [2].…”

The photovoltaic systems are electrical, electronic, and mechanical elements. These systems also face different environmental and operating conditions susceptible to failure. In addition, photovoltaic systems can be the only source of electricity generation, and an affectation on the energy supply can harm the community. In many places, photovoltaic systems are the only source of energy because they are not part of what is known in Colombia as the National Interconnected System (SIN). Which comprises the direct connection between large generators (hydroelectric and/or thermal plants) and consumers. In fact, PV system damage would affect food refrigeration or everyday things like charging a cell phone. Therefore, it is necessary to register, monitor the operation elements of PV systems, and develop strategies that allow the diagnosis to detect faults. In this work, we propose a fault-diagnosis using the PV systems measurements that is, power converter, photovoltaic panels with also mathematical models to determine the deviation between the estimated and measured signals as voltages and currents.
