TÓM TẮT
Today, the microgrid system is attracting the attentionof many researchers because it brings plenty of benefits tothe conventional power system such as enhancing the reliabilityof the system, reducing the transmission cost, and diversifyingenergy sources. In fact, a microgrid system is a small-scale of adistribution system including three main elements: (i) distributedresources, (ii) storage system, and (iii) measurement system. Themain purpose of a microgrid system is ensuring the continuoussupply energy in a small or isolated area, thus it has two mainoperation modes: (i) independent and (ii) connected to the mainpower grid. One of the main challenges of the operation ofa microgrid system is the smooth and optimal shift betweenthese two operation modes in cases of any contingencies fromboth sides. Thus, the operation of a microgrid system requiresdesigning various advanced control methods for this activity, inwhich the hierarchical control technique is widely using in thereal application. Therefore, an overview of this method is verynecessary for the research community since there are many workshave done in recent years. In this paper, the authors present thehierarchical control technique and focus on investigating variousmethods of the primary control of this technique because thislevel is responsible for the independent operation mode of amicrogrid system known as the main advantage of a microgridsystem.
