“…The single-line diagrams of the developed PVGs models according to the control modes and their capabilities are depicted in Figs.2 and .3 , for Model 1 (constant PQ) and Model 2 (constant PV) ,respectively. There are various possibilities for inverter transfer functions; however, the following two are probably the most appropriate [8]:…”

the present paper investigates the effect of penetration of photovoltaic generation (PVGs) systems on the transient and small signal stability. Recently interest in photovoltaic (PV) power generation systems is increasing rapidly and the installation of large PV systems or large groups of PV systems that are interconnected with the power system grid is accelerating despite their high cost and low efficiency due to environmental issues and depletions of fossil fuels. Photovoltaic generators (PVGs) have significant impacts on the existing power systems, these impacts may be either positively or negatively depending on many factors such as PVGs location, size and inverter characteristics. The eigenvalue analysis and the transient analysis of the system are done without any PVGs penetration and with PVGs penetration and then the results are compared. The investigation is applied on IEEE-39 bus test system. The stability analysis is carried out using simulation program of power system analysis tool box (PSAT).

“…There are different possibilities for converter transfer functions; however, the following two models are probably the most appropriate ones [19]: 1) the first-order function with unity steady-state gain; and 2) the closed-loop controller transfer function. Moreover, both provide very similar results and hence the first one is adopted in this paper.…”

<span>With increasing implementation of Wide Area Measurement Systems (WAMS) in power grids, application of wide area damping controllers (WADCs) to damp power system oscillations is of interest. On the other hand it is well known that rapidly increasing integration of renewable energy sources into the grid can dangerously reduce the inertia of the system and degrade the stability of power systems. This paper aimed to design a novel WADC for a utility-scale PV solar farm to damp out inter area oscillations while the main focus of the work is to eliminate the impact of communication delays of wide-area signals from the WAMS. Moreover the PV farm impact on inter area oscillation mitigation is investigated in various case studies, namely, with WADC on the active power control loop and with WADC on the reactive power control loop. The Quantum Particle Swarm Optimization (QPSO) technique is applied to normalize and optimize the parameters of WADC for inter-area oscillations damping and continuous compensation of time-varying latencies. The proposed method is prosperously applied in a 16-bus six-machine test system and various case studies are conducted to demonstrate the potential of the proposed structure.</span>
