Power management systems for voltage control in probabilistic simulations

摘要

Sustained integration of distributed renewable energy sources, especially photovoltaic generation in low voltage grids, has driven the need to expand grid capacities in recent years. Solutions to find an economic justifiable approach for main operation in an aging grid environment have become indispensable. This paper highlights the design of a probabilistic simulation environment and two methods of voltage regulation using photovoltaic inverters. Furthermore it provides the possibility to rate both methods taking all conceivable grid states into account. Thereby the simulation is based on actual, measured field data instead of standardised profiles. The aim is to create a simulation environment in which different grid situations can be simulated while the voltage levels are affected by different voltage regulation methods. This allows distribution system operators optimizing their grid planning by adding unconventional methods of influencing the voltage at lowest levels. Especially low voltage grid simulations with few grid participants and critical network states are lacking accuracy, when modelled by standardized profiles, will benefit from this approach.
