Energy management system for combined renewable generation, storage and conversion (EMERGE model): Renewable Hybrid Power Plant Optimization
report
In order to accelerate the integration of renewable intermittent generation, such as wind and solar photovoltaics (PV), these assets can be combined in a Hybrid Power Plant (HPP) with energy storage, such as batteries, as well as conversion to different energy carriers, such as hydrogen and heat. Such an integration in an HPP can yield highly predictable generation, resulting in higher and more stable revenues, more flexible control that increase grid infrastructure utilization while reducing curtailment. This work details the methodology to model such HPPs and optimize its operation to maximize the profit margin in different energy markets. The Energy Management systEm for combined Renewable Generation and storagE (EMERGE) model com bines the main technical and economic aspects of an HPP into a single package, which allows for scheduling and planning of the HPP for the long and short term future, followed by simulation of the realized operation. The economic aspect of the EMERGE model uses optimization algorithms for the HPP assets to schedule their operation for the upcoming day, in the most profitable sense. The technical package within the EMERGE model then uses a representation of each HPP asset to simulate the actual day operation, identifying the resulting energy surplus and deficit of the plant. As shown at the end of this study, this combination of economical dispatch and the resulting technical analysis positions EMERGE to aid in preparation for small scale testing in a lab setting and model validation, before full-scale imple
