How does energy storage capacity affect total dispatch cost?

Therefore, the lower the capacity of energy storage in operation is, the higher \ (CVaR\) of total dispatch cost is. Figure 7 shows how \ (CVaR\) of total dispatch cost changes with the ratio of total energy storage capacity in the revised IEEE 118-bus system.

Does energy storage capacity change with (CVaR) of total dispatch cost?

The changing trend of energy storage capacity with \ (CVaR\) of total dispatch cost is the same as that of the revised IEEE 30-bus system. As shown in Figs. 6 and 7, when the energy storage system's operational capacity is more than 80% of the total energy storage capacity, \ (CVaR\) of total dispatch cost reaches the minimum values.

How does wind power uncertainty affect economic dispatch problem?

The influence of wind power's uncertainty on the economic dispatch problem is mainly about the balance of electric power. A wind-storage combined system helps deal with the impact of wind power uncertainty in power balance by charging in or discharging from the energy storage system according to the wind power error.

So far, the dynamic economic dispatch model based on \ (CVaR\) is MINLP as: The nonlinearity of AC power flow constraints in ( 39) makes the MINLP is still challenging to solve.

Does wind-storage combined system have an optimal power flow?

In this paper, based on the operation cost of the wind-storage combined system, \ (CVaR\) method is used to deal with the possible risks caused by uncertainty. Based on \ (CVaR\), we establish a dynamic economic dispatch model of the wind-storage combined system, which has considered AC optimal power flow.

Why do operators face risk when deciding the dispatch schedules?

Because of the uncertainty of wind power output and energy storage capacity limitation, operators face certain risks when deciding the dispatch schedules for power systems.
