Technical Assistance to the Renewable Energy and Energy efficiency programme in Jordan – REEE II

Non-synchronous power production from wind and solar PV provide no damping effect on frequency or voltage excursions, making it difficult for the grid to maintain the stability target of damping within 10–20 seconds following a disturbance. Studies in Europe and the US have shown that when renewable power production approaches 50% of total production, there is a need to consider additional practices or infrastructure to bolster the dynamic frequency and voltage response of the grid. This study was performed for the purpose of Jordan’s transmission network system operator – NEPCO.

The scope of the Study was to:

• Update the earlier dynamic analysis of NEPCO’s grid work based on the latest schedule of renewable power additions in DigSilent Power Factory software tool,
• Identify transient stability issues introduced by renewable power production for the years 2018 and 2020,
• Identify Voltage static stability issues for the years 2018 and 2020,
• Identify Frequency stability issues for the years 2018 and 2020 for two cases:
• NEPCO network connected to Egypt network.
• NEPCO in island mode.
• Recommend mitigation strategies and infrastructure, including battery storage.

Type of services provided:

• Transient stability analysis;
• Frequency stability analysis;
• Static voltage stability analysis.
• An interim workshop to present the results of the draft analysis.
• Recommendation of mitigation strategies, including infrastructure such as battery storage.
• Final workshop
