Therefore, it is suitable for large-scale long-term storage to cope with the seasonal imbalance caused by fluctuations in new energy output or the intermittency of solar and wind power generation, thereby alleviating the long-term uncertainty of the system.
Multi-type energy storage, promisingly, can take full advantage of the complementary strengths of the two storage types to make up for the disadvantage that a single type of energy storage device cannot meet the actual application needs in various respects.
In order to maintain the charging and discharging capacity of the power-type storage, it conducts corresponding optimization control of the output through a fuzzy control strategy for maximal use of energy storage and a corresponding increase in the capability of the scheduled-wind-power-output tracking.
Therefore, it is imperative to strategically plan energy storage resources, leveraging the unique characteristics of different types of storage to tackle the imbalance issues in power systems [17, 18]. Current research by experts and scholars has extensively addressed the issue of seasonal imbalance in electricity supply.
From the numerical values in the table, it can be inferred that considering marginal costs and the combination of different types of energy storage can improve the overall economic viability of the system while ensuring normal system operation. Table 3. Description of the cases.
