Introduction

The Study is initiated by EU-funded UNDP CEDRO and GEF-funded UNDP DREG and executed by the German firm ProfEC

The study delivers recommendations and guidelines for theestablishment of a National Grid Code for the interconnection ofLarge Scale Renewable Energy (RE) Plants (PV and Wind) biggerLarge Scale Renewable Energy (RE) Plants (PV and Wind) biggerthan 1MW

Currently, the Interconnection of RE systems is NOT regulatedy, y gtechnically nor legally

These guidelines are tailored to the Lebanese case and shared


today on a semi-technical level

Measurements taken by BRSS (functional since September 2014)

Data downloaded from some M3 meters installed inside EDL Data downloaded from some M3 meters installed inside EDL transmission substations

Data collected from power plants (Zahrani, Beddawi), remote p p ( , ),areas (Sour, Nabatieh, Kobayyat, Zahle, etc.), and nearby areas (Beirut)

f h ll d h ld f ?Assessment of the Collected Data: What would RE serve for?

The RE installations do not represent a high % of generation The RE installations do not represent a high % of generation.They do not have considerable effect on the grid.

Overloading problems should be analysed with suitable Overloading problems should be analysed with suitablemodelling to assess whether grid reinforcement should beundertaken

PV plants can compensate for the excessive consumption at itsPCC (e.g. with Q provision)

The targeted guidelines serve to avoid the possible frequentdisconnection and/or curtailment of RE plants: inefficient or non-economic operation of the plant, while the international standards

and codes in countries, whose grids are more stable, aim forneutralizing the possible negative effects of the intermittent REplants, such as over-voltage or over-loading problems


i f h d i i hb i d i il iOverview of Other Codes in Neighboring and Similar Countries

EN 50160:The tolerance band for the frequency deviation is ±1% for 99.5% of the time along the yearThe tolerance band for the steady‐state voltage deviation at the end‐user (i.e. LV level) is ±10% for 95% of the 10‐minute average values along the year

German technical guidelines for generating plants connected tothe medium-voltage network

Guidelines of neighbouring countries (Egypt, Jordan): very closeto the German guidelines



G id li f R bl E G id I t ti /C dGuidelines of Renewable Energy Grid Interconnection/Code

Applicability and Preconditions of Installationpp y

The adoption of these guidelines and their applicability in Lebanon can go through several iterations of discussions between g gthe stakeholders and relevant authorities

Connection to the grid should be agreed with the Grid Operator (GO) on a case-by-case basis during the planning phase

The GO may demand modifications and completions to existing plants or to those under construction as far as this is required for secure operation


secure operation



Determination of Grid Connection Point

The GO shall determine the appropriate point of connection which ensures secure grid operation by performing several load g p y p gflow calculations with suitable grid models

The GO shall perform worst-case analysis tests: Maximum feed-in of all RE plants and minimum load consumption

The RE Plant Developer (REO) should be responsible for the connection facility to the grid in agreement with the GO (e gconnection facility to the grid in agreement with the GO (e.g. installing the required line)

If the grid needs reinforcement measures (e.g. adding new line,


g ( g g ,replacing lines or transformers) for the connection of the RE-generator, the GO will then be responsible for this installation
