The interest in self-consumption of PV electricity from grid-connected residential systems is increasing among PV system owners and in the scientific community. Self-consumption can be defined as the share of the total PV production directly consumed by the PV system owner.
Most of the papers examine PV-battery systems, sometimes combined with DSM. The results show that it is possible to increase the relative self-consumption by 13–24% points with a battery storage capacity of 0.5–1 kW h per installed kW PV power and between 2% and 15% points with DSM, both compared to the original rate of self-consumption.
The major components of a standalone solar PV system with pumped storage include a power generator (PV array), an energy storage subsystem (consisting of two reservoirs, penstocks, pumps, and turbines/generators), an end-user (load), and a control station. The system is illustrated in Fig. 1.
This review paper summarizes existing research on PV self-consumption and options to improve it. Two options for increased self-consumption are included, namely energy storage and load management, also called demand side management (DSM). Most of the papers examine PV-battery systems, sometimes combined with DSM.
Pumped storage is proposed for stand-alone photovoltaic systems. The system's size, simulation, and optimization are carried out.
