国际能源转移的协调和大多数国家快速增长的分散能源资源（DER）的整合都为避免电压频段违规和线路过载带来了新的问题。传统的方法通常是基于全局离线调度下的全局可用信息和依赖于迭代过程，既不能保证收敛，也不能保证执行时间。在本文中，我们专注于电力网络的稳定性问题的基础上广泛分散（可再生）能源。在本文中，我们将介绍一个扩展的DEZENT算法，一个基于多代理的协调系统DER，允许在恒定的和预定的时间的可行性验证。我们给出了一个数字的例子，表明我们的方法的合法性，并提到正在进行的和未来的工作，有关的实施和利用。
Both the coordination of international energy transfer and the integration of a rapidly growing number of decentralized energy resources (DER) throughout most countries causes novel problems for avoiding voltage band violations and line overloads. Traditional approaches are typically based on global off-line scheduling under globally available information and rely on iterative procedures that can guarantee neither convergence nor execution time. In this paper we focus on stability problems in power grids based on widely dispersed (renewable) energy sources. In this paper we will introduce an extension of the DEZENT algorithm, a multi-agent based coordination system for DER, that allows for the feasibility verification in constant and predetermined time. We give a numerical example showing the legitimacy of our approach and mention ongoing and future work regarding the implementation and utilization.
