Effect of a New Smarts Photovoltaic Inverters Connected with a Distribution Networks in Algeria

The distribution network of electrical energy, by its current structure, is not designed for the rising reception of solar photovoltaic (PV) array. Indeed, the insertion of a large number of PV systems induces overvoltage issues which, depending on the network load states, can lead to noncompliance with the admissible voltage values by the electrical grid code. In many countries, such as Algeria, it led to the revision of standards concerning the connection to the public distribution network of distributed renewable production. The new grid code requires flexible operation of the production plants, which must be able to dynamically modify the active and reactive power according to the network parameters (i.e. the frequency and the local voltage of the network) on command local or by following external commands. Therefore, this work aims to study the use of an intelligent inverter in a critical photovoltaic installation, where relevant voltage fluctuations exist. A case study, with real network parameters monitoring data and measurements, is discussed in order to show how the “intelligent” functionalities of the new inverters can be implemented for the integration of PV installations in low voltage distribution networks.
