Sizing of Hybrid Energy Storage Systems Using Recurring Daily Patterns

A hybrid Energy Storage Systems (ESS) consists of two or more energy storage technologies, with different power and energy characteristics. Using a hybrid ESS, both high-frequency and low-frequency power variations can be addressed at the same time. …

A method for sizing centralised energy storage systems using standard patterns

Low Voltage (LV) distribution networks with high penetration levels of photovoltaics have to tackle various challenges such as overvoltages, voltage fluctuations, reverse power flows, and non-coincident demand and local generation. Energy Storage …

Industrial demand-side flexibility: A benchmark data set

To cope with the new demands of an electrical grid based on mostly renewable energy, more flexibility on the demand-side is needed. To test new demand-side management strategies, energy consumption data sets which come with some information about the …

Assessment of unsupervised standard pattern recognition methods for industrial energy time series

Finding and extracting standard patterns in energy time series is very important to many real-world applications. Hence, there exists a multitude of pattern recognition algorithms with a majority of them being supervised ones. The advantage of …

How much demand side flexibility do we need? Analyzing where to exploit flexibility in industrial processes

We introduce a novel approach to demand side management: Instead of using flexibility that needs to be defined by a domain expert, we identify a small subset of processes of e. g. an industrial plant that would yield the largest benefit if they were …
