Abstract :

Optimal switching has been proposed as a tool to improve the utility of the electricity grid among researchers in the electricity industry. In fact, according to Kirchhoff's rules, the restriction of the transmission of power from one path entails restrictions on the power passing through the corresponding parallel paths. Thus, in some operating conditions, opening a transmission line reduces the parallel paths and constraints imposed and, consequently, improves the network operating conditions. The effects of micro switching on market power in the power system are discussed first. To this end, the competition boundary problem has been developed to consider micro-switching. In this problem, the application of linear-integer models obtained on test networks shows that micro-switching can affect market power in a power system. This effect is further enhanced by the increase in HHI. Also, this effect is even greater at high load levels. This indicates the undesirable effect of micro-grid switching on market power if used without regard to market power. The following is a model for optimizing the micro-network periodic switching as a tool for system deployment to reduce the periodic cost of network deployment considering the market power of the actors. The results show that the optimal periodic switching of the microprocessor can reduce the operating costs of the whole period by considering the market power of the actors. Also, it reduces the market power of the actors compared to the case of micro-grid switching.
