Dynamic energy management on a hydro-powered smart microgrid

Abstract

Penetration of renewable energy-based microgrids onto the legacy grid is in demand to solve the global energy problems and the environmental issues. This paper attempts to employ dynamic energy management on a Grid-Connected Smart Microgrid (GCSMG) energized by a Micro Hydro Power Plant (MHPP) sans governor control. Frequency control of such SMGs poses a challenge as the latter is distributed. The concept of Dynamic Energy Management (DEM) plays a significant role in accomplishing the frequency control without perturbing the controlling facility in the conventional grid. DEM is a concept of controlling the charge-discharge transactions on the energy storage modules to oppose the frequency excursions on the grid. Support Vector Machine (SVM) algorithm is employed to automate DEM operation. The Dynamic Energy Management System (DEMS) is implemented on a Field Programmable Gate Array (FPGA) as the response time is critical for this application. The DEM scheme is validated on the SMG simulator in the Renewable Energy Laboratory of Amrita Vishwa Vidyapeetham University, Coimbatore.
