“…They also mentioned that additional hydroelectricity can be generated since the water volume is increased due to lower water evaporation while the capacity factor is increased by 20%. Ravichandran et al [25] have investigated the use of FPVs in Aswan reservoir in Egypt. The authors stated that the total power of the two existing hydropower plants in Aswan reservoir is at 2.65 GW while two FPV systems, at 5 MWp, each can be installed in the two dams.…”

Floating solar photovoltaics in water bodies is a novel clean energy technology which has been developed rapidly during the last decade. The current work investigates the possibility and the potential of installing floating photovoltaic systems in the existing hydropower plants in Greece. Studies related with the use of floating photovoltaics in water reservoirs in Greece are limited so far. The characteristics of the existing 24 hydropower plants in Greece have been used for the estimation of the solar photovoltaic systems which can be installed in their water reservoirs. It has been found that the nominal power of these solar energy systems which can be installed in their water reservoirs, covering 10% of their water surface, is at 3,861 MWp while the annual generated electricity at 5,212.35 GWh corresponding at 10.04 % of the annual electricity demand in the country. The capacity factor of the integrated solar and hydro power systems is increased by more than 20%. The research indicates that the existing hydropower plants in Greece can host, in their water dams, floating photovoltaic systems generating significant amounts of green electricity while they also result in many environmental benefits. These novel solar energy systems can contribute, together with other benign energy technologies, in the achievement of the national and EU target for net zero carbon emissions by 2050.

Dynamic stability is considered a vital issue in modern power systems. In this work, a robust design is proposed for the stability improvement of grid-connected hydro-turbine generators using the adaptive concept-based Electro-Search optimizer (ESO). In this regard, we provide a dynamic stability analysis of a hydro-turbine generator located at the Aswan High Dam, where proportional integral-derivative power system stabilizer (PID-PSS) is examined for a single machine connected to the Egyptian power system (EPS). The PID controller is developed in the synchronized EPS to significantly mitigate lowfrequency oscillations due to various expected faults and undesirable operating conditions. Comprehensive simulation analysis is performed using Matlab/Simulink considering the synchronous machine rotor speed, mechanical and electrical output powers, field and terminal voltages. The operative performance of the introduced adaptive PID-PSS based ESO is assessed against the conventional system (i.e. without PSS) and system with standard PID-PSS under normal operating conditions where the effect of a 3-φ short-circuit fault is subjected at the grid bus. The findings prove that the proposed adaptive strategy can effectively maintain the dynamic stability of the main grid against fluctuations.

To date, the grid-connected solar photovoltaic (PV) system has drawn consideration from researchers and academicians due to the speedy improvement and the declining price of solar panels. The proficiency and dependability of a grid integrated PV system rest mainly on the power conversion unit and the proper controlling mechanism. This paper introduces a novel asymmetric hexagonal-shaped fifteen-level inverter designed to feed a grid-integrated solar PV system. First, it aims to reduce the number of components and thereby decrease the installation space and cost of the multilevel inverter. Moreover, it has a low total blocking voltage (TBV) and total device rating (TDR) and uses few switching devices for generating per level of output voltage. The proposed topology utilizes only eight switching devices for generating fifteen levels at the output, which is lower than conventional multilevel inverter topologies. Here, a low-frequency modulation scheme using the half-height (HH) method generates switching pulses to minimize the complexity. The proposed multilevel inverter topology is also validated through the simulations in the MATLAB SIMULINK environment. The proposed inverter need for filters is illustrated according to different grid codes for integrating PV systems to the grid.
