“…Thus, this indicator shows the direct relation between (1) the locals, who are supposed to be the first beneficiary of the solar energy produced by the PV parks located in a certain rural or urban settlement, and (2) the different category of land necessary to supply electricity from a PV park. As a result, this indicator could support the idea that this type of renewable energy to be more environmentally friendly more sustainable, the PV farms should be produced and consumed locally [37]. In the study area, the values of the solar electric footprint register values varying from 0.74 sqm/inh.…”

Increasing the share of renewable energy has become one of the key actions Romania has assumed under the Europe 2020 strategy targets on climate change and energy (a.k.a. European 20-20-20 targets). Romania benefits from a wide variety of renewable energy sources (RES) -wind, solar, hydro, geothermal and biomass. Among the RES types, solar resources have started to significantly contribute to the electricity mix. Thus, under the rapid transformation and growth of the renewable energy sector, understanding the impacts of Photovoltaic (PV) parks is essential to avoid the potential negative consequences. Hence, the current study is seeking to assess the environmental and socioeconomic impacts of PV parks in Centre Development Region (CDR). The region is located in the central part of Romania covering 14.3% of the country's surface and holding nearly 12% of its population. It corresponds to the central and southern part of the Transylvanian Depression and the surrounding frame of the Carpathian Mountains. The evaluation relies on several environmental and socio-economic indicators. E.g. share of PV parks/land use category /main soil type; distance to forests, waters, Natura 2000; no. of jobs created during the construction/operation of the PV parks; the value of PV parks investment; the impact on the local budget. For the current assessment, 44 PV parks were identified and mapped covering a total area of 415 ha.

The main objective of this research is to propose an active and reactive power injection control in order to mitigate voltage sags. The proposed control strategy works in conjunction with a modified version of an automatic voltage regulator (AVR), where it will act on the active and reactive powers injected by the inverter to reduce the effects of voltage sags. In this way, the control will avoid possible shutdowns and damage to the equipment connected to the grid. The voltage improvement can be perceived for consumers connected to the power system. Modifications in AVR model and parameters are performed to speed up its performance, thus identifying the short-duration voltage variations (SDVV) and, consequently, the control acts to alter the powers, decreasing the active power injection and increasing the reactive power based on inverter capacity during the momentary voltage dip (MVD). Finally, when the fault is cleared, all values return to the pre-fault condition, so that the inverter only operates with active power. A 75 kW three-phase grid-connected photovoltaic system (GCPVS) equipped with the proposed control was inserted in a distribution grid of the city of Palmas, state of Tocantins, Brazil, and all of the computer simulations were performed on the Matlab/Simulink®.
