PROMOTION OF RENEWABLE POWER PRODUCTION FOR SELF-CONSUMPTION

Unconventional power sources are becoming an increasingly important part of energy systems around the world, both because of the research effort and political will involved in their development, and because of the rising price of traditionally produced power. 

Solar energy is one of the officially recognised renewable energies.

In view of the Client's power needs and the opportunity to use the roofs for power generation, it was intended to build a plant to produce and use the energy produced by the Client for self-consumption and for power injection into the National grid.

So, the project consisted of a photovoltaic system with an installed power of 398 kW, on the roof of an industrial hall belonging to the furniture factory Prestige Mob in Balotesti, Ilfov county.

The photovoltaic power plant is connected to the 0.4kV voltage level in the general electrical panel of the Client's existing complex. The power plant injects electric energy electricity into the grid of the Distribution Operator (E-Distribution) thus having the quality of „Prosumator”(power consumer and producer at the same time). The file for obtaining this status is in progress. Thus, the location will become an "injection into the grid" supplier.

The construction variant of the investment consists of photovoltaic panels that are connected in series of maximum 20 modules by insulated conductors of Cu 6 sqrmm, so that the open circuit voltage of a string (series of panels) must not be higher than the maximum input voltage of the inverter (1100V); 4 inverters of 100kW will be installed, their role being to convert the direct current produced by the photovoltaic panels into AC.

The inverters will take DC power during the voltage and current variation intervals at the output of the PV modules and deliver a constant AC voltage to the output.
