Virtual gas storages 

VIRTUAL GAS STORAGES

Several gas storages can be grouped in single virtual gas storage to optimize gas storage operations within a Gas Market Area. From the perspective of gas market participants such approach allows for sending nominations for one, virtual storage instead of multiple storage facilities. The aim of the Storage System Operator is to distribute nominations between physical gas storages, taking into account costs of operation as well as technical limitations of gas flow rates for each storage facility. 

SUPPORT FOR ACTIVITIES OF VIRTUAL GAS STORAGES

Due to differences in gas storages equipment, storage type and current filling level, cost of injecting or withdrawing gas may wary significantly between physical gas storages. With so many factors to consider finding the best nomination distribution is a difficult task.

vSMS takes into account all abovementioned factors to calculate cost optimal nomination distribution plan, using models of operational costs and technical limits characteristics of all physical gas storages.

Combining vSMS with Storage Operation Expert allows for accurate and up-to-date characteristics to be used in vSMS optimization.

SOE calculates maximal gas flow rates and operational cost values for variety of gas storage states and gas flow rates achievable during vSMS optimization horizon. In case of gas storage connected to multiple gas market areas, nominations submitted on coupling point not included in a virtual storage are considered as constrains and influence calculation of technical limits and cost values.

vSMS optimization and SOE characteristic calculation are designed to fully utilize scalability and hardware concurrency of modern servers. This is crucial in order to meet short time response on client nominations while performing state of art. and resource intensive calculations.
