The power spectrum density of unbalance power

In order to check the superiority of the hybrid Camptothecin storage system for peak shaving strategy, a simulation has been carried out. Fig. 13 gives the performance comparison between the hybrid energy storage system and independent energy storage system under given unbalance power condition. The capacity requirements of energy storage systems used in simulation are shown in Table 6. For a given unbalance power condition, the hybrid energy storage system (bulk and small) and the independent bulk energy storage system are employed in a same system configuration. It can be seen from Fig. 13 that the power output of hybrid energy storage system has a better congruency than the power output of bulk one on following the unbalance power. It's worth noting that the power output of independent small energy storage system has the best fitness with the unbalance power demand due to its shorter response time. However, the independent small energy storage system must made up by plenty of single units to reach the required capacity in the same configuration condition, resulting in a complex problem in control strategy design.
