View Product DetailsAs Bosnia and Herzegovina accelerates its commitment to the Energy Community Treaty and aligns with the European Union’s 2030 Climate and Energy Framework, the Canton of Sarajevo faces a pivotal structural shift. Historically dependent on legacy thermal power plant baseloads (such as TE Kakanj and TE Tuzla) and aging 110kV/20kV distribution feeder topologies managed by Elektroprivreda Bosne i Hercegovine (EPBiH), Sarajevo's grid infrastructure is undergoing an aggressive modernization cycle to absorb non-dispatchable solar energy.
The surge in utility-scale solar PV applications across Herzegovina and Canton Sarajevo has created localized voltage volatility, transformer congestion, and severe ramp-rate constraints. Without advanced Smart Solar Grid Integration systems featuring dynamic reactive power support and grid-forming inverter controls, distribution networks risk frequency instabilities and curtailment.
Achieving seamless integration into the Sarajevo energy corridor requires robust system engineering capable of delivering Information Gain and operational resilience. Smart solar grid integration is no longer merely about stepping up AC voltages; it encompasses real-time edge telemetry via IEC 61850 protocols, dynamic droop control for frequency regulation, integrated high-capacity battery energy storage systems (BESS), and seamless diesel-generator synchronization for mountain telemetry stations and suburban industrial zones.
Sarajevo’s unique topography—encircled by the Dinaric Alps—presents specific microclimate operational challenges. Mountainous microclimates induce abrupt solar irradiance shifts, leading to cloud-edge effect spikes of up to +30% nominal PV output within seconds. High-density commercial clusters in Novi Grad, Ilidža, and Centar encounter distinct localized challenges:
Engineered for high availability, power quality compensation, and full compatibility with NOSBiH (Independent System Operator in BiH) SCADA control networks.
Unlike traditional grid-following inverters that trip during line faults, our advanced hybrid units provide synthetic inertia, active voltage support, and seamless island-to-grid transitions within 10ms.
Custom-engineered 1000kVA to 3000kVA 20kV/0.4kV oil-immersed and dry-type distribution transformers equipped with automatic tap changers (OLTC) specifically tailored for EPBiH substations.
Integrated Modbus TCP, DNP3, and IEC 61850 communications interface seamlessly with localized EMS (Energy Management Systems) for predictive analytics and dynamic tariff optimization.

Our smart grid integration equipment—including transformers, hybrid inverters, and utility BESS units—comes pre-configured with grid protection relays compliant with EN 50549-2 and local EPBiH distribution guidelines. They support active voltage control (Q(U) and P(U) curves), dynamic frequency regulation, and automated power factor correction to ensure grid stability at 20kV interconnection points.
Grid-following inverters rely on a solid utility grid voltage wave to operate. When the grid experiences sags or brownouts (common during peak winter loads in Sarajevo), traditional inverters trip offline. Grid-forming inverters construct an internal voltage vector, allowing heavy industrial machinery to continue operating seamlessly while buffering grid fluctuations via LiFePO4 battery banks.
Our 215kWh and 5.015MWh containerized energy storage systems incorporate liquid thermal management units (HVAC) and intelligent cell self-heating algorithms. This ensures LiFePO4 battery chemistry operates strictly within optimal temperature ranges (15°C to 25°C), preventing lithium plating and maintaining full energy throughput down to ambient temperatures of -25°C.
