Energy Management in the Decentralized Generation Systems Based on Renewable Energy—Ultracapacitors and Battery to Compensate the Wind/Load Power Fluctuations (original) (raw)

2015, IEEE Transactions on Industry Applications

This paper presents the energy management for the Decentralized Generation Systems (DGS) using the wind turbine with photovoltaic panels (PV) and the energy storage devices. For a high penetration level of the Wind/PV generation, the energy storage device with a fast response is necessary to cover the shortfall or overflow of generation due to sudden variations of the wind or the sun. In the more, the requested energy by the residential appliances presents the random behavior which can be lower or higher than the produced energy from the renewable sources. Using the wind turbine and the PV power generation system with energy storage will reduce the fluctuations of the wind power and the load ones. The energy storage system requires capital investment, so, it is important to estimate the reasonable storage capacities without an overflow size for the desired applications. In addition, a good strategy for energy management is necessary to reduce the variations impacts of the wind energy and the load for the battery and the residential appliances. The contribution of this paper is focused on energy management based on the frequency approach using the wind/load's fluctuating power sharing, and the polynomial controllers. This method enables firstly, to reduce for the battery and the micro-grid the impacts of the micro-cycles due to the wind/load's power fluctuations. In the secondly, it allow to estimate the energy storage capacity without the overflow size. The performances of the proposed method are evaluated through some simulations, and the experimental tests, using the summer load profile and the winter ones.
