The causes of such disturbances can include the high inrush currents occurring when the step-up transformers of distributed energy resources are energized. The mitigation of such transients through controlled switching is impeded by the presence of inverters on their low voltage side. Indeed, most circuit breakers in such installations are three-pole gang-operated. The control strategy for such breakers leverages the presence of residual magnetic flux in the iron core of the de-energized transformer, but DER inverters tend to erase that residual flux. A novel method combining flux conditioning and controlled switching was developed to compensate for this drawback and eliminate, virtually in full, the transformer switching transients. This paper reports on a full demonstration of the method on a transformer tied to a 25-kV distribution line first attached to the main grid, and then to a microgrid's battery energy storage system.","PeriodicalId":319119,"journal":{"name":"2022 IEEE Green Technologies Conference (GreenTech)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116243860","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}

There are several factors which inhibit the production of bioH2 such as oxygen (O2) production and a sufficient glucose concentration. A sufficient glucose concentration is vital for fermentative bioH2 yield; however, an insufficient glucose concentration may lead to halt the process. Whereas the production of O2 during the biophotolytic process is the primary inhibitor of bioH2 yield using algal biomass. It can be overcome using the co-culturing of algae and aerobic bacteria. For this purpose, activated sludge from a wastewater treatment plant was served as a source of bacteria in order to regulate O2 during co-culturing with Chlorella vulgaris (CCALA 256). It was observed that the co-culture with 1:1 v/v (algae : activated sludge) produced the highest amount of 1,177 mL/L of bioH2 with a minimum O2 content of 82 mL/L in six days of incubation as compared to the previous studies in which pure bacterial cells were used. The rest of the gas composition was mainly carbon dioxide (CO2) 34% and Nitrogen (N2) 15%, with no methane (CH4) production. Furthermore, a continuous supplementation of 1.5 g/L of glucose was also observed to be the enough to produce 1,084 mL/L of bioH2. It was also observed that anaerobic conditions, in result of co-culturing, may lead to trigger the hydrogenase activity in living algal cells which enhances the biophotolytic hydrogen production along with photofermentative hydrogen production. The substantial improvement in bioH2 production indicates the algal-activated sludge symbiosis as an alternative to pure algal-bacterial co-culture, which is source of green energy generation and waste energy utilizing process.","PeriodicalId":319119,"journal":{"name":"2022 IEEE Green Technologies Conference (GreenTech)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134531717","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, regulated reverse power flow from multiple sites can cause multiple problems including overvoltage. Although active power curtailment is an effective way to mitigate problematic reverse power flow, it inherently penalizes customers at remote locations in radial feeders. In this paper, we present a fairness-based energy coordination strategy enabling customers to share the responsibility of voltage regulation in distribution systems. We consider multiple fairness schemes and demonstrate dividing the burden proportionally according to each customer's capacity. The fairness-based energy coordination problem is solved in a distributed fashion that enables robustness to partial grid outages and limits the data sharing across ownership boundaries. We demonstrate the proposed approach using a modified IEEE 13-bus test feeder and a test harness that wherein greedy customer-led controls introduce overvoltage conditions unless control actions are taken. Results confirm that the proposed approach can successfully mitigate overvoltage without locational favoritism. Introducing fairness increased the aggregate PV curtailment by 0.64 percentage points compared to a fairness-agnostic scheme.","PeriodicalId":319119,"journal":{"name":"2022 IEEE Green Technologies Conference (GreenTech)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116966429","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}

As a result, BESSs generate significant revenue for their operators by participating in ancillary services such as the energy arbitrage and frequency regulation markets. Therefore, BESS operators can benefit from a model that allows them to optimize the bidding process for providing services while also optimizing scheduling in a way that best exploits each BESS cycle by simultaneously stacking various grid services. Estimating maximum BESS revenue is crucial to establishing financial sustainability for investors. In this paper, a BESS optimization model for multiple grid applications is proposed to estimate maximum daily revenue with an appropriate focus on maintaining the longevity of the BESS. The model aims to maximize the revenue generated by a BESS by allowing the system to participate in the energy arbitrage and frequency regulation markets at the same time. In this proposal, a new BESS scheduling method, tested using historical PJM market data, is used to improve revenue generation from providing ancillary services through effective and optimized bidding into the PJM regulation market based on buying/selling to/from the energy markets. The model is formulated as a mixed-integer linear programming (MILP).","PeriodicalId":319119,"journal":{"name":"2022 IEEE Green Technologies Conference (GreenTech)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126916931","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}
