But unfortunately, it was noted that the system stability is inversely proportional to the compensation level. This phenomenon is called a sub-synchronous resonance (SSR). SSR has a detrimental influence on the system's safety and stability. Thyristor controlled series capacitor (TCSC) is one of the most methods used for damping SSR and improving system stability. In this paper, appropriate values of TCSC parameters are identified. The ratio of TCSC inductive reactance to the TCSC capacitive reactance, TCSC impedance characteristic, the ratio of the TCSC capacitive reactance to the capacitive reactance of the fixed series capacitor, and different synchronization signals are studied. Additionally, the TCSC constant power control based on the P and PI controllers are compared. In order to analyze the SSR phenomenon in a doubly fed induction generator (DFIG)-based wind farm connected to TCSC, IEEE first benchmark model (FBM) is modified. MATLAB software is utilized to demonstrate the results.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128263763","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 early detection of pre-mature failures, indoor accelerated testing is performed according to the different International Electrotechnical Commission (IEC) standards. Herein, multiple characterization tools are used for detection and analysis of defects and degradation observed under such tests. Visual inspection forms the primary and standard form of defect detection after these test procedures. However, there is absence of a single fixed, ready-to use source of guideline for such inspections. Also, there is less emphasis on the microscopic inspection, and in-depth detailing of cell and module components and defects. This paper presents detailed guidelines for macroscopic and microscopic reporting of cell and module information, with component wise defect details pre- and post-testing. This list would be useful for module record keeping and will facilitate recording of information which would be useful for further reliability analysis.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488957","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 main objective of this study is to review the strategies of virtual inertia, which are used to compensate for the required inertia to reduce frequency deviation. The stability issue regarding virtual inertia estimators integrated with power system is also a challenge, which is reviewed in this study. A modified power system based on an inertia estimator with a compensator is suggested using the modified techniques presented in recent manuscripts. The most published manuscripts in the field of the following scenarios: (i) load frequency control with renewable energy resources and (ii) load frequency control with virtual inertia are statistically analyzed and the high cited manuscripts related to these research gaps are discussed in detail. The new direction of this review study is suggested to continue improving the virtual inertia estimators by authors.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134504078","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 impact these energies on the environment has led modern societies to seek sustainable alternatives to meet industrial and industrial needs and requirements ever-increasing daily life. This approach has led to the implementation of renewable energy sources.More and more countries are being made aware of the essential nature of the advance of renewable energy in the fight against climate change and of increasing access to energy for the benefit of populations still deprived of any modern energy service.Wind energy is one of the forms of renewable energy; it takes its name from Eole, the name given to the god of the wind in ancient Greece. It is an energy that is directly drawn from the wind using a wind turbine device. The development and exploitation of wind energy has increased in recent years, especially in countries.Wind energy is now attracting the interest of several research teams. These systems that produce electrical energy from the wind can be a technological and economic alternative to the various sources of harmful energy exhausting at the same time.The purpose of this work, we will study the direct vector control of the DFIG based on the orientation of the stator flux, used to make it work as a generator. The latter highlights the relationships between stator and rotor magnitudes. These relationships will make it possible to act on the rotor signals in order to control the exchange of active and reactive power between the stator of the machine and the network.

The objectives set in the first step were to improve and optimize the performance of photovoltaic panels integrated into the building wall using the passive regulation method by coupling them to a macro encapsulated phase change material. In the second step, our objectives were to highlight the impact of the integration of these systems on indoor thermal comfort and on building efficiency. It was revealed that a Building Integration of PV systems causes a significant increase in indoor air temperature. However, for the South direction, the addition of Phase Change Material plays an important role in reducing the heat transfer rate to the room. In fact, the maximum temperature of the south-facing wall has been reduced by around 2.2 ° C when attaching Phase Change Material layers behind the Building Integrated Photovoltaics systems. The average temperature of the vertical and inclined BIPV cells temperature, at midday, is reduced by about 3 °C and 25 °C, respectively, due to the integration of PCM at the back sides of the systems. It is concluded that coupling the Building Integrated Photovoltaic system with a layer of phase change material and integrating such system with the room envelope is an interesting solution to improve the performance of photovoltaic systems and to be closer to the thermal comfort of the individual simultaneously.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130889043","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}
