On the contrary, the proposed parallelism control directly controls their output current of each VSI, leading to achieving an excellent load sharing performance without knowledge of their rated-powers and how many VSIs are connected.

This system is flexible to apply to various PV configurations. One-day simulations based on measured PV and electrolyzer characteristics demonstrate very high maximum power point tracking (MPPT) efficiency (higher than 99.9%) and average power conversion efficiency (94.0%) on a clear sunny day. Annual energy production is expected to increase by 8.5%-point compared with a single converter system using one of the best commercial converter. The key elements of the high efficiency are the new system topology, a specially designed phase-shift full-bridge converter and a control method “P&O with converter scoring” algorithm.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"96 1","pages":"441-446"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76604784","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}

Our results indicated that the municipal subsidies significantly induced the installation of rooftop PV although their effects depended on the several conditions such as income. On the other hand, we found no evidence of an effect on rooftop PV's system price reduction in municipalities with higher exposure to the subsidies. Subsidies rather seemed to have an effect to raise prices up.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"18 1","pages":"828-832"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75226539","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 wind generator model is based on doubly fed induction generator (DFIG) and were developed using Matlab/Simulink. The presented methodology can be used to map the impact on operation of different types of control, the time of day and the available wind speed and it is not limited only for DFIG. The results have shown that the methodology helps to find zones were the combination of wind speed, load demand and control strategy can lead the system to voltage levels outside the standard limits.
