Review of Flexible Electricity Tariffs and Electricity Price Signals and Factors Involved in the Design of Smart Grids

In the last two decades, due to the growing trend of electricity consumption and limited government resources, the issue of privatization and restructuring of the electricity industry has been considered. Exhaustion of existing network equipment on the one hand and the emergence of new technologies on the other, the electricity industry has faced new challenges. Overall, the smart grid provides a solution to the current network's challenges, including reliability challenges, environmental challenges, and energy efficiency challenges. In general, it can be said that the smart electricity network is the result of the addition of two-way communication technologies to the traditional electricity network, which paves the way for the use of various technologies to create new capabilities to the electricity network. Installation of multi-tariff meters in order to apply multi-tariff rates for all three-phase electricity subscribers as well as high-consumption single-phase subscribers in tropical and non-tropical regions in our country for several years. Tariffs have been imposed. In order to encourage industries to make optimal use of electrical energy and create the necessary economic incentive to optimize the load curve of industrial plants in the peak load of the national network and the use of facilities, the Ministry of Energy in the third shift, most three-shift and two-shift factories to supply, install And the operation of two- and three-tariff meters has started. Today, most research and industrial centers, along with the world's power companies, have come to the conclusion that smart grids are a necessity. The smart grid is not a newly established network, but an evolved form of today's network that must address the weaknesses of the current network. The capacity of the transmission system should increase significantly in the coming years, as customer consumption will increase. For example, the heating system with heat pumps is rapidly evolving and the use of electric vehicles is increasing day by day. Therefore, system investors should think about developing and creating new capacities for the transmission network.
