One of the main capabilities grid-forming converters is ability to operate in both islanded and grid-connected modes. The work autonomously behave as an AC voltage source when they are isolated from bulk power system. In a mode, it necessary for them offer set enhancing system inertia strength. A converter may experience significant fluctuations voltage, current, frequency transition occurs. Th...

The battle for electricity customers in an increasingly competitive and deregulated market environment is one of the challenges facing the electric power utilities of today. Customers expect a reliable and efficient supply of power from their utilities. One of the advantages that a distributed generator (DG) can provide to the electric utility and to customers is the possibility of improving th...

In this paper, a strategy based on Genetic algorithm for optimal allocation of reactive power resources in distribution system with microgrid is presented. In the proposed approach uncertainty in power generation of renewable based DG is considered. The main objective is to allocate fixed and switched capacitors as reactive power resources for voltage control within the desired limits on a dist...

The increasing penetration of dc distributed energy resources (DERs) and loads has motivated the utilization microgrids (MGs). In this paper, a new two-level control scheme is proposed for accurate power sharing appropriate voltage regulation in MGs during islanded operation mode. primary level, P-· V droop method to eliminate dependency among DERs on line resistances. Since deviates derivative...

The idea of a microgrid is created by utilizing more diverse ac or dc distributed generation (DG) sources along with an energy storage system (ESS) and loads. The most efficient and reliable selection of ac and dc microgrids is a hybrid ac/dc microgrid. The hybrid microgrid largely overcomes the shortcomings of standalone ac or dc microgrids. A bidirectional interlinking converter (BIC) is util...

This paper presents the importance of deployment of distributed energy resources as a promising aspect which is emerging as a future power system as microgrid in the power community worldwide. The basic concepts of microgrid technology including its operational and control techniques are presented briefly in simplified manner. The application and prospect of microgrid in Indian power scenario a...
