Kong et al. [7] established the optimal distribution model of byproduct gas based on dynamic integer linear programming (MILP), which enabled enterprises to produce and use energy media more reasonably. Zhao et al. [8] proposed a method to reasonably determine the penalty factor by using Pareto optimality.
Distributed energy storage is an essential enabling technology for many solutions. Microgrids, net zero buildings, grid flexibility, and rooftop solar all depend on or are amplified by the use of dispersed storage systems, which facilitate uptake of renewable energy and avert the expansion of coal, oil, and gas electricity generation.
For purposes of comparison, the current storage energy capacity cost of batteries is around $200/kWh. Given today''s prevailing electricity demand patterns, the LDES energy capacity cost must fall below $10/kWh to replace nuclear power; for LDES to replace all firm power options entirely, the cost must fall below $1/kWh.
Storage energy is an effective means and key technology for overcoming the intermittency and instability of photovoltaic (PV) power. including households and enterprises, in Shanghai City over 24 h in 2016, this study analyzes the costs, benefits, internal rates of return, and investment recovery periods of distributed PV (DPV) and ES
