Title (DE) STATE OF CHARGE MANAGEMENT IN BATTERY SYSTEMS
(EN) STATE OF CHARGE MANAGEMENT IN BATTERY SYSTEMS
(FR) GESTION D'ÉTAT DE CHARGE DANS DES SYSTÈMES DE BATTERIE
Abstract: front page image
(DE)10 CH-14112-WO-PCT ABSTRACT The present invention is concerned with strategies to manage the State of Charge (SoC) of a battery which is used to limit ramp rates of a renewable power plant. The proposed 5 management system relies on a SoC target that is defined by the energy to be absorbed or provided, either in a worst case or most likely (statistical, forecast) scenario. It facilitates smaller dimensioning of the Battery Energy Storage System (BESS), while still guaranteeing the required level of availability. The SoC management likewise reduces the energy throughput, and thus both improves system efficiencies through reduced losses and extends 10 the lifetime of the battery through reduced cycle degradation. Both aspects contribute to lowering costs of the BESS. Integration of relevant environmental conditions and / or available short term predictions further improves the resulting economies. The SoC management system is conceptually simple and can easily be implemented even on a cheap controller hardware with little computational power.15 Fig.2
(EN)The present invention is concerned with strategies to manage the State of Charge (SoC) of a battery which is used to limit ramp rates of a renewable power plant. The proposed management system relies on a SoC target that is defined by the energy to be absorbed or provided, either in a worst case or most likely (statistical, forecast) scenario. It facilitates smaller dimensioning of the Battery Energy Storage System (BESS), while still guaranteeing the required level of availability. The SoC management likewise reduces the energy throughput, and thus both improves system efficiencies through reduced losses and extends the lifetime of the battery through reduced cycle degradation. Both aspects contribute to lowering costs of the BESS. Integration of relevant environmental conditions and / or available short term predictions further improves the resulting economies.

(FR)La présente invention concerne des stratégies pour gérer l'état de charge (SoC) d'une batterie qui est utilisée pour limiter les taux d'accroissement d'une centrale à énergie renouvelable. Le système de gestion décrit repose sur une cible de SoC qui est définie par l'énergie à absorber ou à fournir, dans le scénario soit du pire des cas soit le plus probable (statistique, prévision). Il facilite un dimensionnement plus petit du système de stockage d'énergie par batterie (BESS), tout en continuant à garantir le niveau de disponibilité requis. La gestion de SoC réduit également le débit d'énergie, et donc améliore l'efficacité du système grâce à une réduction des pertes et étend la durée de vie de la batterie grâce à une réduction de la dégradation de cycle. Les deux aspects de l'invention contribuent à abaisser les coûts du BESS. L'intégration de conditions environnementales pertinentes et/ou de prévisions à court terme disponibles améliore encore les économies qui en résultent. Le système de gestion de SoC est de conception simple et peut être facilement mis en œuvre même sur un matériel de contrôleur bon marché à faible puissance de calcul.
