能源互联网中多种储能的协调

Energy storage coordination among various energy networks in Energy Internet

能源互联网已成为又一代工业革命的主题,而储能作为能源互联网发展的关键技术支撑,受到越来越多的关注。能源互联网由各种能源网络结合在一起构成,各能源子网之间可以提供能源支持,因此在整个能源互联网中会出现能源存储的冗余。各种储能的协调配合有助于降低能源储存的总需求,提高经济效益。本文首先指出各种储能协调的必要性,根据能源互联网中各种能量需求的特点,提出了协调原则和能源互联网储能协调的实施步骤。以经济效率和能源利用率为优化目标,给出了适当的必要约束。应用粒子群优化算法进行优化协调,并在模拟的情况下得到两种具有较高的经济效益和能源利用率的储能协调方案。本文对能源互联网各种储能的有效协调具有参考价值。

Currently,Energy internet has become the theme of the new industrial revolution.As one of the key supporting technologies of Energy Internet,energy storage has attracted more and more attention.Since several energy networks are combined together to construct a composite Energy Internet,they may provide more or less energy supporting to each other,so there will be some redundancy in the total of energy storage among the whole Energy Internet.The coordination and allocation of various energy storages is helpful to reduce the total demand for energy storage and improve the economic efficiency.This paper points out the necessity of the coordination of various energy storages firstly.According to the characteristics of different energy storages and various demands in Energy Internet,the coordination principles and the implementing steps of energy storage coordination in Energy Internet are presented in the paper.Based on the principles,economic efficiency and energy utilization rate are set as the optimal objectives,and the proper necessary constraints are given.The optimal coordination is solved by particle swarm optimization,and two coordination schemes of various energy storages with high economic efficiency and proper energy utilization rate are obtained in the simulation case.Valuable reference for the effective coordination of various energy storages in Energy Internet is provided in this paper.
