The global requirement for sustainable energy provision will become major problem for the future because the environmental effects of fossil fuels become apparent. This trend has a makeable encouragement for private participation in capacity expansion in a marketoriented industry organization. In addition, installation of small generators located close to the load centres, may give more flexibi...

Connections of distributed generation (DG) systems to distribution networks are increasing in number, though they may often be associated with the need of costly grid reinforcements or new control issues to maintain optimal operation. Appropriate analysis tools are required to check distribution networks operating conditions in the evolving scenario. Load flow (LF) calculations are typically ne...

In this paper a technical review of parallel operation of power electronics inverters for load sharing conditions in distributed generation (DG) network is presented. Emphasis is given to parallel operation of Active Power Filters (APFs) as they are widely used to mitigate load current disturbances into DG networks. Discussions on recent advances in control strategies as applied to APFs are pre...

1214304-8585-IJET-IJENS © August 2012 IJENS I J E N S Abstract— In this paper we present the design of an Adaptive overcurrent protection for Distribution Power Systems with penetration of Distributed Generation, based in a proposed methodology. The methodology takes into account typical protection schemes, normative, general protection requirements, protections coordination and distributed gen...

In this paper, a modified version of Imperialist Competitive Algorithm (ICA) is proposed for the optimal energy management Microgrid (MG) with Parking Lots (PL) and Distributed Generation (DG) units. A 24-h scheduling participation in DG units electric vehicles PLs two scenarios done. The are divided into seven group that each has different trip behavior. Therefore, should be done such way as t...

Distributed Generation (DG) is the production of electricity from a variety renewable energy sources that closer to customer and load. The addition distributed generation distribution networks alters characteristics system has an influence on its protection coordination. Relay plays critical function in protecting power various problems. coordination reduces relay operating time avoids failure....

This paper presents a network reconfiguration method for power flow optimization and, consequently, loss reduction in distribution networks with Distributed Generation (DG). The network reconfiguration problem is formulated and solved using a simple linear programming approach. Optimal configurations are determined by considering the effects of DG outputs, load variations, and various other con...

Distributed generation (DG) offers several benefits to the electrical system, such as reduction of losses and improvement voltage profile. DG can be maximized when allocation sizing are optimal — a problem known Optimal Sizing Placement Generation (OSPDG). This paper presents new meta-heuristic that associates PSO (Particle Swarm Optimization) with L´evy flights (LF) solve OSPDG, identified in ...
