Time series based distribution grid planning approach with decentralised voltage regulation

摘要

One of the most crucial constraints in operation of power systems is keeping the permitted voltage intervals. Uncontrolled distributed generation may cause voltage problems in distribution grids, due to static power factors. Recent converter technologies allow variation of the power factor. Therefore, the consideration of units with these technologies in the planning process respects their ability of providing reactive power. Then, unnecessary network extension can be avoided. In this paper, an extension of an agent-based simulation platform for distribution networks is presented. The decentralized generation units are represented by agents that are able to adjust the reactive power consumption or in-feed according to the network status. In combination with the voltage control the presented system provides realistic loading and voltage time series for a selected grid section. With this simulation the utilities are able to determine the probability of loading situations and plan their network in a more efficient way.
