Droop Control of Hydro Power System in OpenHPL
Keywords:parallel operation of hydro powers, multi-generator system, droop control, OpenHPL
AbstractOpenHPL is an open-source hydro power library for modeling, design, and analysis. Currently, OpenHPL consists of mechanistic models for waterways from a reservoir to tailrace, Francis and Pelton turbine models, a simple generator model, hydro power speed governor model, etc. However, the library lacks a controller for the parallel operation of hydro powers. This paper mainly focuses on extending OpenHPL with power-frequency droop control for a multi-generator system. Two simulation case studies are carried out for the parallel operation of hydro power units.
