Our reference projects from Africa

Reference Project Mali
Customer: ECM Sarl (Energy Company of Mali)
Technical, economic, financial, environmental and social feasibility study for photovoltaic systems of 40 MWp in Kambila and 50 MWp in Safo” in Mali.
- Grid and grid stability studies (including but not limited to the study of
short-circuit currents, load studies, power quality studies, stability studies, including grid connection costs and barriers) ; - The stability study of the national interconnected grid (NVN).
– Calculation of the load flow :
o Normal operation established,
o Evaluation of short-circuit currents.– Dynamic behaviour:
o static stability,
o Transient stability.
– Analysis of harmonics. - connection to the network.
– Analysis of the existing load in the vicinity of the selected sites, taking into account the specifications of the network in that area ;
– Connection requirements;
– Analysis of the influence of PV power plants on the grid, especially on voltage, frequency,
harmonics, fluctuations, etc. - Dynamic study essentially aims at the following points:
– Validation of the capacity maximum exchange capacity included in the static study ;
– Analyzes of network security to determine strategies to maintain acceptable operating conditions during normal operation and to secure the system during a failure.
– Assessment of transient stability, which aims to verify the immunity of the network to strong disturbances being tested by
Disorders of different types and accordingly
mainly to faults three-phase interference, loss of a power unit production loss, transmission line loss and load loss.
– Assessment of the stability statics of the interconnected electrical system with a view to assessing its stability in the event of small disturbances
