Improved active power sharing strategy for ELC Controlled Synchronous Generators Based Islanded Micro Grid application

Abstract

This paper presents an Improved Active Power Sharing Strategy for Electronic Load Controller (ELC) Controlled Synchronous Generator Based Islanded Micro Grid (MG) Application. ELC regulated synchronous generators operating in parallel forming a MG is considered. Existing MG at Baglung District (Interconnected seven nearby Micro Hydro Plants with cumulative power output of 132 kW) was taken as a reference case for the study. Current active power sharing strategy was realized by considering MG with three generators and new concept was proposed to minimize the existing problem on power sharing. The control strategy is presented only for the MG operated in islanded mode. The case is designed and simulated in MATLAB using Simulink. This study does not consider the reactive power flows and sharing issue. This scheme can be efficiently used in MG Application.
