Funding entity Inter-American Development Bank (IADB)

The IADB is currently in a preliminary stage of a project in Haiti, which consists on the installation of a solar photovoltaic (PV) plant and a battery bank. The aim of the battery bank is to tackle short-term power fluctuations and contribute to primary frequency support. This project studies the frequency stability of the system and the optimal sizing of the battery bank. Technical recommendations related to the PV plants and the battery bank are also given.

Research topics:
• Isolated systems: islands, microgrids, off-grid
• Steady-state: load flows, analysis of power system constraints, optimal load flows, voltage control ancilliary service,short-circuits, protections in transmission and ditribution networks
• Stability: large disturbance stability, tuning of frequency loadshedding schemes, excitation control, small disturbance stability, tuning of power system stabilizers, identification of AVR and governor models
