Modelling should consider added flexibility, eg grid services, sector coupling benefits, eg utilising excess wind production, and access to electricity markets, eg time-of-use tariffs. This paper presents a two-step methodology for sizing heat pump and thermal storage systems with a time-of-use electricity tariff. The first step is a modelling method for decentralised energy systems, with the broader aim of assisting planning-level design, and consists of resource assessment, demand assessment, electrical components, thermal components, storage components, and control strategies. The second step is a parametric analysis of heat pump and thermal storage size combinations. This is then applied to a sizing study for an existing residential district heating network including a time-of-use electricity tariff. The performance metrics:% of heat pump thermal output at low-cost period,% of heat demand met by heat pump, electricity import cost, and capital cost, were plotted and tabulated to compare sizing combinations. Graphs explore the operation of the heat production units and the thermal storage. Future development involving use of model predictive control and grid services, and alternative applications including operational planning and feasibility studies, are then discussed.","PeriodicalId":424726,"journal":{"name":"Proceedings of the 13th International Renewable Energy Storage Conference 2019 (IRES 2019)","volume":"1584 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123371808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For large and powerintensive consumers, for instance, in the industrial sector, peak shaving with BESS can be an attractive option to reduce the consumer’s network charges as well. This study focuses on the potential of BESS for peak shaving application in the nonresidential sector in Germany, considering four types of nonresidential buildings: office, fire station, hotel and sports center. Results provide an overview of profitable BESS sizes depending on specific installation costs and grid demand limit. Additionally, PV systems could help to reduce the necessary storage capacity for maintaining the maximum demand within the desired grid demand limit. Furthermore, peak shaving with BESS could enhance the grid support characteristics of the buildings, although the corresponding BESS sizes would not be economically feasible under current pricing conditions. However, the enhancement of the grid support characteristics could become an incentive, if consumers would get the opportunity to exploit wholesale market price signals.

Lithium-ion battery energy systems (BESS) are, owing to their characteristics, uniquely poised to support and augment the functioning of the energy supply system. It is crucial to identify and analyze the factors which play a role in their efficient and effective operation. This paper identifies and analyses three such major factors application scenarios, power electronics with power distribution strategies, and battery parameters which influence the efficiency of a BESS. The applications analyzed are primary control reserve and peak shaving. Two Power electronics topologies and their load distribution strategies are presented, with their influence on the conversion efficiency being evaluated subsequently. Two commercial lithium-ion technologies a Lithium Iron Phosphate cathode/Graphite anode cell and a Lithium Nickel Manganese Cobalt Oxide cathode/Graphite anode cell are also simulated for two states of health (SOH). The aged cells are considered to possess a capacity equal to 80% of original nominal capacity and a cell resistance twice that of the new cells. It is found that the system conversion efficiency can be greatly improved in applications with low active chargebased and high temporal utilization ratios by deploying a suitable power electronics topology and load distribution strategy. For applications with high active charge-based and low temporal utilization ratios, the battery resistance and the serial-parallel combination play an important role.","PeriodicalId":424726,"journal":{"name":"Proceedings of the 13th International Renewable Energy Storage Conference 2019 (IRES 2019)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126903106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In electricity autonomous cases a battery system stands as prerequisite to succeed renewables time shifting due to the intermittent nature of decentralized generation. In the present study the local autarky in the electricity sector is examined for a system composed of a photovoltaic installation, a wind farm, a biogas combined heat power plant and a battery. The selected storage system is a Lithium Ion battery and two different modelling alternatives have been applied. Consequently, the two system versions have been tested for three autonomous case study regions in north, central and south Germany. The system is subsequently operated, and the minimum battery capacity is estimated for each case study based on dynamic simulations. Simulation results indicate that the autarky in the electricity sector can be feasible, but the capacity is underestimated almost up to 30%, if the aging effect of the battery is neglected and the efficiency grade is considered steady. Moreover, outcomes show that the calculated battery capacity is higher for the south city due to the solar power variability as an outcome of the seasonal","PeriodicalId":424726,"journal":{"name":"Proceedings of the 13th International Renewable Energy Storage Conference 2019 (IRES 2019)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123814249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, high capital and maintenance costs become the main barriers to its implementation. To overcome the challenges, using the battery storage in multiple applications and incorporating optimization method are proven to be able to increase its economic benefits. Accordingly, the underlying question of this thesis is whether the economic benefits from using the battery to accommodate energy arbitrage and manage demand charge while also implementing optimization method can hurdle its high costs. During the optimization process, battery usage cost which sometimes being neglected in prior studies is deliberated, and its impact on the total cost of the battery is analyzed. The dispatch schedule optimization is built using mixed-integer programming algorithm with the objective function to minimize lifecycle costs of the battery storage. The optimization is simulated for 8-days time horizon. Sustainable floating residentials, a microgrid project in Amsterdam, is used as a study case. The microgrid component consists of solar photovoltaic, load, and battery. Vanadium-redox battery technology is investigated using the optimization method. Dayahead based rate is used as the electricity pricing scheme. The results demonstrate that utilizing the battery for multiple applications might increase its economic benefits and overcome its high initial and operating costs. Another notable result is that the battery usage cost tends to have a significant impact on the total costs of the battery. Considering battery usage cost in the optimization method could reduce the total costs.","PeriodicalId":424726,"journal":{"name":"Proceedings of the 13th International Renewable Energy Storage Conference 2019 (IRES 2019)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129194561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
