With the promotion of renewable energy utilization and the trend of a low-carbon society, the real-life application of photovoltaic (PV) combined with battery energy storage systems (BESS) has thrived recently. Cost–benefit has always been regarded as one of the vital factors for motivating PV-BESS integrated energy systems investment.
Storage helps solar contribute to the electricity supply even when the sun isn’t shining. It can also help smooth out variations in how solar energy flows on the grid. These variations are attributable to changes in the amount of sunlight that shines onto photovoltaic (PV) panels or concentrating solar-thermal power (CSP) systems.
While energy storage is already being deployed to support grids across major power markets, new McKinsey analysis suggests investors often underestimate the value of energy storage in their business cases.
The investment cost of energy storage system is taken as the inner objective function, the charge and discharge strategy of the energy storage system and augmentation are the optimal variables. Finally, the effectiveness and feasibility of the proposed model and method are verified through case simulations.
Existing compressed air energy storage systems often use the released air as part of a natural gas power cycle to produce electricity. Solar power can be used to create new fuels that can be combusted (burned) or consumed to provide energy, effectively storing the solar energy in the chemical bonds.
Coupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most. Peak power usage often occurs on summer afternoons and evenings, when solar energy generation is falling.
