The Dominican Republic has set a national target to reduce its green-house emissions by 25 % (compared to 2010 levels) by 2030. To achieve this goal, the Dominican Republic is planning the integration of large amounts of variable renewable energy technologies (VRE’s) into its power system, mainly wind and solar PV energy.

The objective of this grid integration study is the assessment of the impact and constraints of the integration of large amounts of VRE’s into the Dominican Republic’s power system on technical operation (contingency analysis, transient stability and frequency stability). Consistent recommendations will be provided to guarantee the security of the system, based on the findings and conclusions of the study.

Findings of the study will aim to support the development and implementation of policies, regulation and operation practices to allow the operability of a future power system in the Dominican Republic with high shares of renewable energy.

Research topics:
• *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
• Isolated systems: islands, microgrids, off-grid : Islands, microgrids, off-grid
