Scheduling Power-Intensive Operations of Battery Energy Storage Systems and Application to Hybrid Hydropower Plants
<|reference_start|>Scheduling Power-Intensive Operations of Battery Energy Storage Systems and Application to Hybrid Hydropower Plants: Classical schedulers for Battery Energy Storage Systems (BESSs) use static power constraints, assuming that the BESS can provide the rated power at any State-Of-Charge (SOC) level and that these are representative of the underlying physical constraints of the system (BESS voltage and current). Static power constraints, however, can generate unfeasible schedules, especially in power-intensive applications, as demonstrated in this paper. This paper derives a set of alternative constraints for the BESS power that are cognizant of the physical limits of the BESS. It is shown that these constraints, developed by leveraging an equivalent circuit model of the BESS, can be formulated as linear inequalities in scheduling problems, thus leaving the properties of the original problem (i.e., linearity and convexity) unaltered. A comparative analysis against traditional schedulers from the literature shows significant reductions in current violations and the generation of feasible schedules. These findings underscore the crucial role of implementing more advanced power constraints of BESSs in power-intensive applications, thereby enhancing the reliability of BESS scheduling strategies.<|reference_end|>
