| 摘要: |
| 储能技术是解决高比例风电消纳问题、提高系统可靠性的有效手段。然而储能不同的功能定位、典型负荷曲线与风电出力曲线的选取等都会影响储能的配置结果。为研究储能配置规律，分别建立了考虑风电不确定性、风电爬坡以及风电消纳问题的多参数储能配置模型。研究储能不同功能定位下的配置情况。在此基础上，基于单一变量原则以及相关性分析，量化研究系统中各类参数对储能配置的影响。算例结果表明：通过风电的合理接入可减少所需配置的储能容量，合理的储能接入节点可有效降低网损；单纯依靠储能解决风电消纳问题时所需配置的储能容量最大；决定储能容量配置的价格型参数主要为分时电价；系统型参数中对储能容量影响最大的是风电装机容量以及峰谷差率。 |

| Abstract: |
| Energy storage technology is an effective means of solving the problem of having a high proportion of wind power consumption and improving system reliability. However, the different function orientation of energy storage, and the selection of typical load and wind power output curves will affect the configuration result of energy storage. In order to study the rules of energy storage allocation, multi parameter energy storage allocation models considering the uncertainty of wind power, wind power climbing and wind power consumption respectively are established. The configuration of different functions of energy storage is studied. Then, based on the principle of single variable and correlation analysis, the influence of various parameters in the system on energy storage allocation is quantitatively studied. The results show that reasonable access of wind power can reduce the required energy storage capacity, and the reasonable access node can effectively reduce the network loss; the maximum energy storage capacity needs to be configured when only relying on energy storage to solve the problem of wind power consumption. The time of use price is the main price determining the allocation of energy storage capacity. Among the system parameters, the wind power installed capacity has the greatest impact on the energy storage capacity and peak valley difference.
