This kind of conventional generation abides for obvious environmental and safety risks regarding maritime transportation, storage and transfer of diesel fuel. Furthermore, there are several costs incurred by this type of generation during a year of energy supply. The Berlenga Project aims for a more sustainable solution for the energy supply of the island while guaranteeing a cost-effective solution and compliance with all its environmental protection measures, as well as adapting the regulatory framework, which was defined before European unbundling directives, forbidding the DSO of having generation activities. Though various solutions and mixed renewables systems were considered, the supply system chosen for the island was a solar + storage + backup diesel off-grid solution, which best responded to the major concerns regarding environmental issues and presenting itself as the most cost-effective solution when in comparison with a submarine cable (both in investment and maintenance).","PeriodicalId":405107,"journal":{"name":"CIRED - Open Access Proceedings Journal","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124597234","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}

Microgrids aggregate multiple production facilities, consumer installations, storage facilities as well as supervision and control tools. They can operate either in grid-connected mode or in an island mode. In the last few years, this concept has been expanding to heat and gas networks and begins to be thought of in a multifluid way. The authors consider the Sustainable Powering of Off-grid REgions (SPORE) microgrid which encompasses Singapore's largest wind turbine, photovoltaic panels, batteries and a power-to-power hydrogen system for powering fuel cell electric vehicles. To achieve a higher efficiency of the energy system and increase the interaction between different energy carriers, ENGIE Lab Crigen has developed an optimisation model for multifluid microgrids operating in island mode. Operational objectives are to minimise the net operating cost of the microgrid while satisfying the demand in electricity and hydrogen and enhancing the flexibility in terms of power supply. Nonlinear dispatch models are linearised to fit the mixed-integer linear programming framework used for higher computational efficiency. To assess the validity of the multifluid optimisation and show efficient interactions between electricity, hydrogen and transportation, standard operating scenarios have been simulated, allowing a day-ahead energy planning.","PeriodicalId":405107,"journal":{"name":"CIRED - Open Access Proceedings Journal","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132769179","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}

Hence frequency stability is one main concern regarding their operation. Load step pre-announcement and a bang–bang controller were proposed and applied in a test islanded microgrid, consisting of a conventional generator, a photovoltaic (PV) generator and a lumped load, to improve the frequency response. In this study, a possible control architecture for the proposed method is illustrated. A sensitivity analysis is conducted to determine the influence of two parameters, preset and total time, on the performance of the proposed control method. Furthermore, the effectiveness of the implementation of load step pre-announcement and bang–bang controller in the test microgrid with different shares of PV is evaluated through simulation results.","PeriodicalId":405107,"journal":{"name":"CIRED - Open Access Proceedings Journal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127896403","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}
