Table 3: _Cont._In smart grid technology, communication between utilities, consumers, and suppliers is of great importance. Consumer satisfaction and a reliable supply of electricity are possible when there is an efficient communication system. The survey conducted in [21; 22; 23; 27; 28; 29; 30] explored different communication media and all the related issues to these networks, which are tabulated in Table 3. The authors in [24] reviewed different security issues related to the communication network in smart grid technology. On the distribution side, smart grid technology plays an important role in minimizing the energy cost by utilizing an energy management mechanism. From a consumer perspective, it is very important to reduce the energy cost in order to pay the minimal electricity bill. Moreover, the supplier wants to minimize the consumers' peak hours demands in order to not operate the peaker power plants which charge them highly. Energy cost minimization, electricity bill reduction, and the curtailment of demand during peak hours need an efficient energy management mechanism. There are various surveys available in the literature that aim to disclose the various aspects of smart grid technology and its applications as energy management solutions for consumers as well as for suppliers. Some authors addressed energy management through using smart appliances at the consumers' premises and smart infrastructure, while some presented smart distributions for energy management.
