Operation of residential hybrid renewable energy systems: Integrating forecasting, optimization and demand response

This paper presents a methodology to systematically formulate a hybrid renewable energy system (HRES), which consists of solar, wind and diesel generator as a backup resource as well as battery storage, from the preliminary design stage to the optimal operation. Detailed modeling of each system component, including photovoltaic(PV) panels, wind turbines and lead-acid batteries, are introduced as the basis for simulation. System sizing considering energy flows is conducted to get the optimal combination of PV and wind generation units. Power management strategies from both the demand-side and generation-side are developed to realize the objectives of meeting the electricity demand while minimizing the overall operating and environmental costs. Real-time weather forecasting and model updating are also integrated into the proposed methodology using a receding horizon optimization strategy.
