PV-Battery-Hybrid-Systems the alternative power generation Conferencia de Energías Renovables, Guatemala, 13 de abril 215 1
History Long history in renewable generation and storage technology Development of steering systems and monitoring concepts for a 2-axistracking and monitoring systems for MW- PVplants. Concept & design skytron monitoring solution Development and implementation of control concepts for different battery chemistries and power levels. e. g.: Lead acid 45kW, 15kWh charging station NaS 1MW, 6 MWh Younicos test facility, Lithium-Ion 15 kw, 15 kwh off-grid Redox-Flow 2kW 4kWh Gildemeister Energy Solutions Cellcube FB 2-4 23-27 27-212 2
Background Solar Power: From a marginal ecological contribution to the backbone of a renewable power supply system dieselgenset Existing Power supply for off-grid-systems Proven technology Delivers inrush and short circuit current Low investment high operating costs Dependency on fuel price development High maintenance effort Sufficient genset capacity is needed to cover load fluctuations 3
Background Solar Power: From a marginal ecological contribution to the backbone of a renewable power supply system dieselgenset PV + dieselgenset = Diesel- genset with Solar PV connected The energy replacement with the PV-system is limited to about 15 to 2% Only daylight consumption can be replaced Running capacity of genset to cover cloud coverage and load changes 4
Background Solar Power: From a marginal ecological contribution to the backbone of a renewable power supply system 1 kwp Solar PV Hourly average power Resolution like it is used in simulation like Homer From 1 AM to 5 PM is minimal output > 3 kw Data interval 1 Hour Thanks to my former colleagues at syktron-energy for kindly sharing these pictures
Background Solar Power: From a marginal ecological contribution to the backbone of a renewable power supply system 1 kwp Solar PV Hourly average power and 1 minute measurements Clouds passing by From 1 AM to 5 PM is min. output < 6kW Power gradients faster than 1 min Data interval 1 Hour Data interval 1 Minute Thanks to my former colleagues at syktron-energy for kindly sharing these pictures
Background Solar Power: From a marginal ecological contribution to the backbone of a renewable power supply system dieselgenset PV + dieselgenset = PV + ESS + diesel + - + - = = + - 7
