Abstract: Energy storage systems (ESS) are indispensable building blocks of power systems with a high share of variable renewable energy.

However, it is inevitable to consider the complicated coupling relations of mobile energy storage, transportation network, and power grid, which can cause issues of complex modeling and low efficiency. To address that, this paper proposes a mobile energy storage dispatch model to minimize the load curtailment.
However, the traditional dispatch methods ignore the battery's dynamic power limit and degradation characteristics, which leads to the mismatched power between ESS dispatch commands and the actual optimal responses, and shortened battery lifetime. This paper proposes a novel battery model to achieve an optimized dispatch of ESS.
Results show that ESS function well on the basis of the proposed model and control scheme, and also demonstrate the superiority of the novel algorithm. Energy storage systems (ESS) are indispensable building blocks of power systems with a high share of variable renewable energy.
In the intra-day stage, the adjustment reserve of generation and AA-CAES can also decrease. In this way, the total dispatch cost decreases. Therefore, by adjusting the confidence level and the quantity of sampling data, the power grid operators can balance the dispatch economy and frequency security. Table 5.
The primary benefits of dispatchable power plants include: These capabilities of dispatchable generators allow: Load matching - slow changes in power demand between, for example, night and day, require changes in supply too, as the system needs to be balanced at all times (see also Electricity).
Mobile energy storage (MES) is a typical flexible resource, which can be used to provide an emergency power supply for the distribution system. However, it is inevitable to consider the complicated coupling relations of mobile energy storage, transportation network, and power grid, which can cause issues of complex modeling and low efficiency.
