Due to government policies and incentives, it will be more popular in the future since it is a free and environment-friendly nature. Besides its advantages, photovoltaic (PV) generation causes some serious problems to the grid. Since PV generation directly depends on the solar irradiance, cloud movements can cause sudden changes on the output of PV power and this results in some power issues in the system such as voltage violations, reverse power flow, voltage fluctuations. These types of issues complicate to maintain voltage within compulsory levels at customer sides. Thus, cloud-induced transients in PV power are seen as a potential handicap for the future expansion of renewable energy resources. This study investigates effects of instantaneous changes in PV power on the customer side voltage levels. Daily PV power output and voltage profiles were simulated using a real-world microgrid design that will be implemented in the Malta College of Arts Science and Technology (MCAST) Campus.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122980097","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}

The linearization procedure is based on first-order Taylor-series expansion and on the computation of the Jacobian matrices of the joint turbine and generator's model. For the approximately linearized model of the power unit an H-infinity feedback controller is designed. This controller stands for the solution of the power unit's optimal control problem under model uncertainty and external disturbances. The computation of the controller's feedback gain requires the solution of an algebraic Riccati equation, which is performed again at each time-step of the control algorithm. The stability properties of the control scheme are proven trough Lyapunov analysis. First, it is confirmed that the controller satisfies the H-infinity tracking performance criterion which ascertains its robustness. Moreover, it is proven that the control loop is globally asymptotically stable. Finally, to implement sensorless control of the power unit the H-infinity Kalman Filter is used as a robust state estimator.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117108157","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}

An increasingly RES penetration and the global decarbonisation and efficiency targets have introduced many challenges, also in Italian energy system, that must be sustained by the Grid Operators. This paper aims to investigate and present a new role for CHP as flexible resources supporting the power grid providing ancillary services, such as voltage and frequency control and at the same time other possible contribution in term of resilience, higher efficiency, emission reduction and greater RES integration. Moreover, the international political and regulatory framework has been analysed and the current debate regarding the role of the CHP as one of the protagonists for the achievement of the national, EU and International energy, climate and competitiveness targets has been reported. Finally, the current barriers to the development of cogeneration and the possible solutions to overcome them have been treated.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132183591","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 particular, a holistic approach for the nZEB microgrid by integrating several improved efficiency generating and consuming devices is presented and thus, the efficiency increase of the whole nZEB is attained. The scheme of the proposed improving interventions aims to the efficiency increase of domestic wind turbines, the higher exploitation of the energy storage system (ESS) and the reduction of the energy consumption of electric motor drives in residential applications, such as elevators, electric roll-up doors, air-conditions, etc. The above efficiency improvement interventions do not only provide reduction of the operating expenses (OPEX) in a nZEB, but they can contribute to the reduction of the required capital expenditure (CAPEX) for transforming a conventional building to nZEB. The latter is attained because, for the same level of energy autonomy of the building and without affecting the comfort of the residents, reduction of the power capacity of the renewable energy sources (RES) and the energy storage capability of the ESS can be accomplished. The methodology of each of the proposed technique is described in the paper and also, selective experimental results are presented that both verify the effectiveness of the theoretical considerations and validate the effectiveness and practicality of the proposed improving efficiency interventions in a nZEB.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131537053","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}
