Distributed Generation Connection Guidelines
• Status:
– Completed draft guidelines. PLN is finalizing based on comments from
Wilayahs
• Involvement:
– Developed Renewable Energy Generation Plant (REGP) Connection
Application and Power Procurement Process
– Technical requirements for REGP: Protective functions,
Voltage/frequency regulation, power quality
– Generation specific requirements: Wind power, solar power
– Testing, certification and commissioning
• Comments:
– In-depth involvement in most aspects of DG connection guidelines
– DG connection guidelines should serve as the rule book for equipment
manufacturers and developers, and significantly streamline approvals

Evaluation of Nusa Penida Wind Farm
• Status:
– Completed site visit, analysis and recommendations
• Involvement:
– Visited Nusa Penida with PLN and Whypgen
– Recommendation to PLN:
• Do not invest in refurbishing turbines as it is not financially viable
• Start from scratch: Perform wind measurement using tall met-masts (60
or 80m), perform wind resource assessment and if project is financially
feasible then install utility scale turbines
• Comments:
– Projects done by government for “other than” financial reasons are
rarely successful
– PLN should not own or manage wind farms; it is best left to private
sector.

Wind Resource Assessment & Financial Feasibility of
Taman Jaya Wind Farm in Sukabumi
• Status:
– Completed wind resource assessment and financial feasibility analysis
• Involvement:
– Worked with Pertamina to assess viability of 10MW wind fram in
Sukabumi
– Analyzed Viron Energy’s wind measurement data
– Performed detailed wind resource assessment using WAsP
– Performed financial feasibility analysis with P75 and P90
– Recommendations: Project is not feasible with the current PPA and
Pertamina’s return on equity hurdle rate
• Comments:
– Pertamina has accepted the recommendations
5
Java-Bali-Madura Grid code enhancements for
interconnecting Wind Power Plants
• Status:
– Completed draft grid code has been submitted to PLN. Presented to Renewable
Energy and System Planning divisions. Awaiting PLN review
• Involvement:
– Developed grid code enhancements for interconnecting 10MW and higher size
wind plants to 70KV and higher transmission lines. Application and Power
Procurement Process
– Developed Connection Code, Operating Code, Metering Code,
Scheduling/Dispatching Code, and Data Requirements Code
– Technical requirements for: Active and reactive power, frequency ad voltage
regulation, Low Voltage Ride Through, protective functions, and power quality
– Generation type specific requirements: Induction versus full power conversion
• Comments:
– Authors of the grid code enhancements for interconnecting wind power plants
– Grid code will be part of PPA for developers
– Grid code should streamline interconnection study & approval process

Steady state modeling for impact of 197+MW wind
power in South Sulawesi
• Status:
– Completed steady state modeling of South Sulawesi system: 2015
scenario with 70MW of wind, 2019 scenario with total of 194.2MW of
wind
– Submitted draft report of the impact study. Presented to System Planning.
Awaiting PLN review and comments
• Involvement:
– Data collection of current network in South Sulawesi and connections to
other provinces
– Steady state modeling using MiPower
– Load flow analysis and short-circuit analysis
– Scenario definition
– Determination of impact under the scenarios
• Comments:
– PLN will use results as basis for interconnecting 3 wind farms of sizes
70MW, 62.5MW, 64.8MW in South Sulawesi
– Recommendations are for PLN to improve system operations practices in
order to integrate wind power successfully
7
Dynamic stability modeling for impact of 197+MW wind
power in South Sulawesi
• Status:
– Completed dynamic stability modeling of South Sulawesi system: 2015
scenario with 70MW of wind, 2019 scenario with total of 194.2MW of
wind
– Submitted draft report of the impact study. Presented to System Planning.
Awaiting PLN review and comments
• Involvement:
– Data collection of current network in South Sulawesi and connections to
other provinces
– Dynamic stability modeling using MiPower
– Transient stability and frequency response analysis
– Scenario definition
– Determination of impact under the scenarios
• Comments:
– PLN will use results as basis for interconnecting 3 wind farms of sizes
70MW, 62.5MW, 64.8MW in South Sulawesi
– Recommendations are for PLN to improve system operations practices in
order to integrate wind power successfully
8
Training on system impact modeling and analysis, hands-on
with MiPower software, wind resource assessment
• Status:
– Completed 5-day training at the PLN Renewable Energy Academy in
Makassar
• Involvement:
– Conducted training on theoretical aspects of system modeling and
analysis in general and with wind generation in particular
– Hands-on training on MiPower, a software for modeling load flow,
short circuit and dynamic stability of system
– Wind Resource Assessment—Wind measurement, wind resource
modeling using WAsP, Average Annual Energy Production
• Comments:
– 25+ attendees from PLN Pusat and PLN regional offices from System
Planning, System Operations and Renewable Energy divisions
– Attendee feedback: Need more training
