Both global climate change and the decreasing cost of lithium-ion batteries are enablers electric vehicles as an alternative form transportation in private sector. However, a high vehicle penetration urban distribution grids leads to challenges, such line over loading for grid operator. In case installation integrated storage systems represent conventional reinforcement. This paper proposes method coordinated control multiple battery energy located at electrical charging parks using linear...
In this paper five different flexibility options are analysed from a techno-economic perspective as alternatives to traditional grid expansion for specific distribution in Germany. The are: two reactive power control strategies with photovoltaic inverters (as function of the feed-in, or voltage at connection point), one residential and large scale battery storage applications (primary reserve autonomous self consumption maximisation strategy control). For pilot located Southern Germany...
Primary control reserve and maximising self-consumption are currently two of the main applications for large-scale battery storage systems. Although being most profitable application batteries in Germany, systems applying primary have not been implemented a grid supportive manner distribution grids yet. Despite current unfavourable regulatory framework reimbursement scheme community electricity storages they potentially more than residential storages, which is mainly due to their economy...
The energy transition towards renewable and more distributed power production triggers the need for grid storage expansion on all voltage levels. Today’s system planning focuses certain levels or spatial resolutions. In this work we present an open source software tool eGo which is able to optimize throughout in a developed top-down approach. Operation investment costs are minimized by applying multi-period linear optimal flow considering infrastructure of extra-high high-voltage (380 110...
In this article we apply the transparency checklist methodology by Cao et al. to a case study evaluate degree of in energy system modelling. We use recent conducted Reiner Lemoine Institut that analyses heat and electricity supply German region. An analysis questions indicates different issues are addressed: transparency, reproducibility quality. The completed with answers regarding its supplementing materials shows large majority (93%) criteria (73%) could be satisfied. However, only...
The rapidly increasing number of implemented photovoltaic (PV) systems in the German distribution grid recent years has led to power quality issues due intermittent generation and reverse flows periods low demand. In order decrease this impact, different solutions are being investigated. aim study is analyze maximum possible relief by using residential PV storage reactive control strategies from viewpoint a system owner. To compare voltage method scenarios hosting capacity used as...
The energy transition towards renewable and more decentral power production triggers the need for grid storage expansion on all voltage levels. Today's system planning focuses certain levels or spatial resolutions. In this work we present an open source software tool eGo which is able to optimize throughout in a developed top-down approach. System costs are minimized by applying linear optimal flow considering infrastructure of extra-high high-voltage (380 110 kV) level. Hence, common...
Efforts to decarbonise the transport sector lead an increasing share of electric vehicles (EVs), which can impose significant stress on future distribution grids. The level is thereby not only dependent number integrated EVs but also existing topology grid and present shares supply demand units. These factors are likely influence strategies help integration EVs, such as utilising EV flexibility through smart charging. We therefore examine different charging distinct types, namely PV-, wind-...
Abstract Energy system modeling has been following the energy transition to investigate challenges and opportunities of future systems on all grid levels. Necessary input for sector-coupled models are residential electricity heat demand curves. The increasing importance distribution grids their requires profiles in high spatial resolution.This paper presents a method assign pre-generated curves georeferenced buildings Germany. We aim at overcoming fundamental shortcomings Standard Load...
With increasing penetrations of distributed energy resources (DERs) introduced to the distribution grids (DGs), these will require reinforcements. This study analyses required grid reinforcement costs for six medium voltage (MV)-grids with underlying low (LV)-grids and different characteristics provide an estimate evaluate cost reduction potential by utilising flexibility from DERs. Therefore, photovoltaic (PV), battery storage systems (BESS), heat pumps (HPs) electric vehicles (EVs) are...

The increasing number of heat pump installations in Germany will require additional grid expansion and reinforcement measures. Grid operators call for measures to block pumps during critical, high load phases. However, the exact implementation possible blocking periods their impact on costs remains unknown. This paper introduces a framework evaluate mechanisms cost, based real-world household profiles. We show that previously suggested approaches literature, such as all peak hours, lead...
