Proportion of offshore wind power equipped with energy storage

How to optimize offshore wind power storage capacity planning?

Firstly, an optimization model of offshore wind power storage capacity planning is established, which takes into account the annual load development demand, the uncertainty of offshore wind power, various types of power sources and line structure.

How big is offshore wind power?

During 2017, a capacity of 3148 MW of offshore wind was commissioned and connected to the grid in European countries, reaching a cumulative total of more than 15 GW . This penetration is continuously growing with the target of 25 GW offshore wind power capacity in total by the year 2020 .

How much electricity does an offshore wind farm produce?

It means that the scale of the lithium-ion battery energy storage system configured for the offshore wind farm with a total installed capacity of 9176.5 MW in the coastal area is 2752.95 MW/2752.95 MWh. At this time, the practical electrical output of the offshore wind farm is 24,225.85 GWh.

How much does offshore wind power storage cost?

Based on the power supply and line structure of the power grid in a coastal area, an example analysis of offshore wind power storage planning was conducted. According to this method, the best energy storage configuration scheme was (0.3, 1), at an annual cost of 75.978 billion yuan.

Why do offshore wind power stations need energy storage?

The lack of peak regulation capacity of the power grid leads to abandoned wind. The installation of an energy storage system is flexible, and the configuration of energy storage for an offshore wind power station can promote it to become a high-quality power supply.

What is the relationship between abandoned wind rate and energy storage configuration?

The relationship between the abandoned wind rate of the offshore wind power and the energy storage configuration scheme is shown in Table 5. Thus, with the further increase in new energy storage power capacity and energy capacity, the abandoned wind rate of offshore wind power gradually decreases. Table 5.
