已经开发了一种简单的概率方法来预测储能能力，以增加间歇性嵌入式可再生能源发电（ERG）在弱电网上的渗透，并提高通过时移输送到网络的电力的价值。本文主要研究了在电压上升会限制电液水平的地方，风力发电机的连接问题。短期存储，覆盖面积小于1h，只能提供少量增加的电量，可以被网络吸收。储存长达一天的时间可以带来更大的能源效益，但成本要高得多。比较了不同可行的蓄电技术在不同时间尺度上的运行适宜性。已经研究了与额定功率和能量容量有关的存储值，以便于适当的尺寸。
A simple probabilistic method has been developed to predict the ability of energy storage to increase the penetration of intermittent embedded renewable generation (ERG) on weak electricity grids and to enhance the value of the electricity generated by time-shifting delivery to the network. This paper focuses on the connection of wind generators at locations where the level of ERG would be limited by the voltage rise. Short-term storage, covering less than I h, offers only a small increase in the amount of electricity that can be absorbed by the network. Storage over periods of up to one day delivers greater energy benefits, but is significantly more expensive. Different feasible electricity storage technologies are compared for their operational suitability over different time scales. The value of storage in relation to power rating and energy capacity has been investigated so as to facilitate appropriate sizing.
