“…There are, in recent literature, several examples of works that have tried to tackle electrical energetic issues from different angles in isolated systems such as islands. Vasconcelos et al (2015) present the main challenges and identifies possible solutions related to the operation of remote, isolated power systems with a large integration of renewable generation, taking as example the real case of the Portuguese-Atlantic islands. Authors looked for the support and improvement of robustness of the operation in terms of fast frequency and voltage control responses using islands of Madeira archipelago as case study.…”

This work is within the scope of set of consultancy studies made for Portuguese islands. It focuses on the integration of Pumped Storage Power in isolated islands. The paper starts to address several power systems circumstances about two Portuguese islands on the energetic level. For each of these islands, an independent examination of the conditions to install a reversible hydro power plant is accomplished. Therefore, the energy volume to be stored due to excess of renewable generation and the ideal power and number of the pumps and turbines to be installed were identified and evaluated for the sake of using the produced energy surplus as to be pumped and later generated. The paper enhances the importance of storing energy in the operation of isolated and small systems with considerable amount of intermittent power resources as well as the conditions for the viability of installing new exploitations of this kind.

“…It needs a special attention on the grid frequency stability control actions [8,9]. Frequency regulation (FR) techniques have been studied widely in the literature [1,[9][10][11][12][13][14][15][16][17][18][19][20]. All FR methods require a reduction over the active power generation on USPVPs.…”

Power Production Losses Study by Frequency Regulation in Weak-Grid-Connected Utility-Scale Photovoltaic Plants

Abstract:Nowadays, an increasing penetration of utility-scale photovoltaic plants (USPVPs) leads to a change in dynamic and operational characteristics of the power distribution system. USPVPs must help to maintain the system stability and reliability while implementing minimum technical requirements (MTRs) imposed by the utility grid. One of the most significant requirements is about frequency regulation (FR). Overall production of USPVPs is reduced significantly by applying FR curves, especially in weak grids with high rate of frequency faults. The introduction of a battery energy storage system (BESS) reduces losses and improves the grid system reliability. Experimental frequency and irradiance data of several weak grids have been used to analyse USPVPs losses related to FR requirements and benefits from the introduction of a BESS. Moreover, its economic viability is showen without the need for any economic incentives.

“…Furthermore, as system inertia plays a vital role in primary frequency control, the presence of inverter-interconnected renewable generation in bulk transmission systems has the tendency to deteriorate frequency stability without proper active power balance management, either by means of storage [11], [12], demand response [13], inertial response emulation control loops for renewable generation [14], etc. Alternatively, Delille et al [15] explore the benefits of load voltage sensitivity for frequency stability improvement.…”

This paper proposes a quasi-steady-state modeling approach for an approximation of long-term frequency dynamics in power systems. A specific phenomenon of concern is an onset of frequency swings during load/generation imbalance scenarios. The effects of system voltage characteristics, system inertia, and, more importantly, damping controllers are explained and quantified using the described quasi-steady-state models. Application of the methodology to a 14-generator benchmark system demonstrates that described models are suitable for simulation of different disturbance scenarios that can trigger frequency instability. Moreover, linearization of the proposed models can provide convenient means for impact assessment and coordinated design of damping controllers. To demonstrate this, coordinated tuning of multiband power system stabilizers to improve frequency dynamics has been performed and validated through nonlinear simulations using a commercial transient stability software.Index Terms-Frequency dynamics, frequency stability, multiband power system stabilizer, oscillation damping, quasi-steadystate models.
