Replacing centralized and dispatchable bulk power production with diverse small, medium-scale, and large-scale non-dispatchable and renewable-based resources is revolutionizing the power grid. The Energy Storage Systems (ESSs) have also been employed alongside RESs for enhancing capacity factor and smoothing generated power.
In this context, energy storage systems (ESSs) are proving to be indispensable for facilitating the integration of renewable energy sources (RESs), are being widely deployed in both microgrids and bulk power systems, and thus will be the hallmark of the clean electrical grids of the future.
Summarizing, in this work a novel energy management strategy of hybrid (PSH-battery) energy storage system operating in an on-grid mode is proposed to supply the load both from VRES and DSS whilst minimizing the interaction with the national grid. This strategy considers the minimum operating limit for the water pump and turbine in case of the PSH.
The Energy Storage Systems (ESSs) have also been employed alongside RESs for enhancing capacity factor and smoothing generated power. This structural transformation has been accompanied by unceasing progress in intermediate modern power converters' manufacturing technology and control techniques.
Grid energy exchange for PV/wind/DSS. Fig. 13, Fig. 14 prove the point that the use of a complimentary storage technology reduces the energy flow between the grid and hybrid system and thereby increases the share of renewables in covering the energy demand, improves the system reliability and boosts the efficient utilization of clean energy.
Abstract: High penetration of renewable energy resources in the power system results in various new challenges for power system operators. One of the promising solutions to sustain the quality and reliability of the power system is the integration of energy storage systems (ESSs).
