Power Losses Management in Electrical Distribution Networks with Renewable Energy Sources: Case Study—Electrica Muntenia Nord Distribution Operator’s 110 kV Grid

Nowadays, there is a growing spread of the unconventional power producers, from renewableRenewables energyEnergy sources: wind, photovoltaics, micro-hydro, biomass, etc. RenewableRenewables power producers (RPP) can cause a sharp increase in technical power losses (TPL). This is a major challenge for electricity distribution operators (EDO). Effective tools and measures are needed to solve this situation. The paper deals with the problem of RPP (photovoltaics and wind) in the high voltage (h.v.)—110 kV—electrical distribution networkElectrical distribution networks (EDN), of the Electrica Muntenia Nord (EMN) EDO. The innovationInnovation brought by this paper is represented by the RPP (injecting power at medium voltage level) global influence analysis (voltage level and power losses), from different areas of the network, for characteristic operating conditions. On the other hand, it is also brought by their influence on specific contingencies.
