Abstract

In conventional networks, power plants are constructed in far distances from cities. They are responsible to supply electrical demand, alone. Long transmission lines act as interface between generators and consumers, which transfer the required electrical power to the loads. The mentioned structure leads to some deficiencies including economic concerns, emission production and loss increment. By appearance and penetration of distributed generation (DG), microgrid (MG) and smart grid concepts, the structure of power networks have changed considerably during recent decades. The appropriate design and operation of MGs are essential in modern smart networks due to their important role. In this paper, improving system voltage stability is got under studied while achieving optimal design for MGs in a radial distribution system. It is considered that the constructed MGs operate in both grid-connected and islanded modes. In other words, separating the designed zones leads to self- supplied performance and voltage fluctuations would be occurred. It is attempted to design MGs in a way that the system voltage stability enhances. In order to obtain reasonable results and perform analytical evaluations, efficient indices are proposed and appropriate formulations and optimization algorithms are presented. The studies are implemented on the PGE 69-bus distribution test system.
