Application of Pumped Storage to Increase Renewable Energy Penetration in Autonomous Island Systems

Pumped hydro energy storage system: A technological review

“…It has been argued by many researchers through experience, experimental work, and modeling studies that the throughput of renewable sources of energy will increase with usage of bulk energy storage options. It has been established that a favorable and realistic way to introduce pumped storage in island systems is based on the concept of hydroelectric power storage operating in a coordinated manner [15][16][17][18][19][20][21]. Furthermore, the usage of bulk energy storage systems has been proven to reduce wastage of renewable energy generation and specially wind energy by 10% [22][23][24][25][26].…”

“…However, the feasibility of pumped storage systems was not proved in the intermediate scenarios of RES integration. A favorable and realistic way to introduce pumped storage in island systems is based on the concept of PHES comprising of wind farms and storage facilities, operating in a coordinated manner [15][16][17][18][19][20][21]. For these reasons, energy storage systems which are able to recover the rejected wind energy [22][23][24][25][26] under economically effective terms [23,27] are widely applied, achieving maximum exploitation of wind energy at both national [28] and community level [29] applications.…”

Pumped storage-based standalone photovoltaic power generation system: Modeling and techno-economic optimization

“…A considerable number of studies have been conducted on utilization of pumped storage to increase the annual share of power supply that can be covered by wind energy, and most of them are focused on autonomous small island system using wind turbine for power generation and power supply [29][30][31][32][33][34][35][36][37]. Several studies have also been presented in pumped storage for PV system integration [38][39][40][41][42][43][44].…”

Συμβολή Στην Ανάλυση Υβριδικών Αιολικών – Αντλησιοταμιευτικών Σταθμών Παραγωγής Ηλεκτρικής Ενέργειας

“…Σχήμα 1.2. Σχηματική αναπαράσταση ενός ΥΒΣ σε απομονωμένο νησιωτικό σύστημα, [33,34] Ο ΥΒΣ περιλαμβάνει ένα (ή πιθανώς και περισσότερα) Α/Π, έναν ΥΗΣ, ένα αντλιοστάσιο και δύο δεξαμενές, με το Α/Π να μην είναι εγκατεστημένο απαραιτήτως στην ίδια ή παρακείμενη τοποθεσία με τα υπόλοιπα. Οι διάφορες υπομονάδες του ΥΒΣ (Α/Π, ΥΗΣ, αντλιοστάσιο) συνδέονται απ' ευθείας στο δίκτυο με ανεξάρτητους μετρητές ενέργειας.…”
