Abstract

In order to increase the amounts of renewable energy accommodated in the system, new tools that take into account the horizon of the decision taken are necessary. Feature like the availability of new information can be included in a dynamic optimization framework and therefore help mitigate congestion in the system and have positive effects on distribution systems. This study proposes a new algorithm and shows some preliminary results for the use of Energy Storage Systems (ESS) interacting with stochastic sources of generation. The initial motivation came from the study of the adoption of renewables for electricity, and how to better harness the power of sources that are inherently oscillatory in power output. The benefits of ESS in a dynamic optimization go beyond the amount of renewable energy actually dispatched in the system. The current debate and probable adoption of electrified transportation will most likely increase the pressure on local distribution systems. However, the availability of distributed energy will also increase, in the form of energy storage, once the interface between the grid and the power sources in the vehicles is developed in a mass scale.
为了增加系统中可容纳的可再生能源的数量,考虑到所作决定的范围的新工具是必要的。新信息的可用性等特征可以包含在动态优化框架中,从而有助于缓解系统中的拥塞,并对配电系统产生积极影响。本文提出了一种新的算法,并给出了一些与随机发电源相互作用的储能系统(ESS)的初步结果。最初的动机来自于采用可再生能源发电的研究,以及如何更好地利用电力输出中固有振荡的能源。ESS在动态优化中的好处超出了系统中实际分配的可再生能源的数量。目前关于电气化运输的争论和可能的采用很可能会增加当地配电系统的压力。然而,一旦电网和车辆电源之间的接口得到大规模开发,分布式能源的可用性也将以能量存储的形式增加。
