Towards performance enhancement of hybrid power supply systems based on renewable energy sources

摘要

In the present study,the design and the implemented operation of an automated control strategy in a Hybrid Power System(HPS)based on Renewable Energy Sources(RES)are analysed.A photovoltaic array and a wind generator serve as the main power sources that cover controllable and non-controllable load demand.A lead-acid battery is used to compensate the inherent power fluctuations(excess or shortage)and to regulate the overall system operation,based on a developed power management strategy.The performance of the automatic control system is evaluated through the real-time operation of the power system where data from the various subsystems are recorded and analysed via distributed data acquisition units and the use of day ahead energy forecasting models.
