The research was carried on the case study farm in Wielkopolska Region (Western Poland) specialized in milk production (600 cows). The results have shown that both analyzed scenarios can give the additional profits to a studied dairy farm. However, the anaerobic digestion can provide more than twice a higher profit (315.6 kEuro) comparing to the composting scenario (148 kEuro). In composting, the biggest part of the generated heat is lost and only 36% can be recovered, which influences on profit decreasing up to 75.5 kEuro (instead of 201.7 kEuro theoretically). The amounts of energy produced in anaerobic digestion technology by CHP unit is almost equal for electricity (1601 MWh) and for heat (1680 MWh). However, the electric energy has several times higher value than heat because of additional subsidies paid by the state.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134166362","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}

NEM allows utility and consumer to mount a bi-directional meter to measure power flow in two directions- one from utility to consumer (import) and another from consumer to utility (export). The consumer’s monthly consumption bill will be calculated based on the net energy measured by the meter i.e. energy drawn from the distribution grid minus the energy delivered to the distribution grid over the stated billing cycle. This study assesses the technical and economic potential and feasibility of net metering system implementation for a rooftop Solar Photovoltaic (PV) in a commercial building.

However, RES are intermittent in nature and the power generated by them fluctuates randomly, due to which, appropriate measures are needed to ensure an efficient and reliable power supply. This paper reviews the state-of-the-art techniques used to mitigate the intermittency of RES in MG. A new classification of intermittency mitigation techniques is presented and a comparison of these techniques is drawn. Based on the reviewed literature, some important research directions to improve the existing intermittency mitigation techniques are proposed. Among these directions, the need to investigate RES complementarity further by characterizing RES, minimization of the cost of energy storage systems (ESS) and development of algorithms for better integration, management and control of ESS and dispatchable generators have been identified as crucial challenges in mitigating the intermittency of RES in MG. In addition, the standardization of communication protocols to ensure interoperability of communicating elements of MG and the use of fast, reliable communication links have been realized as fundamental requirements for a MG to be able to mitigate intermittency through appropriate techniques, such as, energy cooperation between MG and demand response management.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"301 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125758706","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}

According to the principle of participating in the demand side response, operation parameters of the household power system are collected and the corresponding values of household load groups are calculated. Based on the calculated composite values, the polymerization process at night is processed. Then the aggregation process is optimized, and a fast aggregation decision tree is established accordingly. The aggregation model based on potential assessment is established according to electricity consumption habits of users and operating characteristics of equipment. The experiment shows that the load response performance of the research method can be better. The user satisfaction is over 90%, the load scheduling time is less than 1.8s, and the daily power consumption of the family can be reduced. This proves that the comprehensive performance of the method can be better and the application effect can be more ideal.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133503488","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}

Therefore, this paper proposes a novel master-slave control strategy based on the proposed adaptive droop control of the voltage source converter (VSC). According to this strategy, the master station operates in constant DC voltage mode as a reference of voltage and other slave stations adopt adaptive droop control with the dead band. When MVDCDS operates in steady-state, the slave stations output constant power to track the setting values, but if MVDCDS suffers from the lager disturbance, the slave stations can automatically switch to the adaptive droop control to rapidly regulate the DC voltage, so that the DC voltage does not overstep its limits. A two-terminal DC distribution system model is established by MATLAB/Simulink to verify the effectiveness of the proposed control strategy.","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133009552","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 normal operation of dry-type transformers faces many challenges, mainly due to the long maintenance period, high reliability requirements and complex offshore power requirements. At the same time, the offshore power system has formed a big data environment. In this context of power system, big data analysis methods are urgently needed. Based on the high-dimensional random matrix theory, this paper firstly considers various factors which have influence on the state of dry-type transformers to construct a condition evaluation matrix, and then analyzes the eigenvalue distribution of the condition evaluation matrix which was formed by time series data. In order to reflect changes in eigenvalue distribution, the mean spectral radius (MSR) was introduced. Through it, we can find the trend of key performance changes, and detect abnormalities in key performance of equipment in time.

The proposed winding successfully offers a high torque and voltage qualities with a low cogging torque. Besides, the stator and rotor core losses are reduced when compared with a three-phase counterpart. Finally, the high phase order of the proposed generator provides a better fault tolerant generator design. A 100kW PM generator with an outer rotor based on the proposed winding layout is designed and simulated using 2D Finite Element Analysis (FEA).","PeriodicalId":140641,"journal":{"name":"2020 4th International Conference on Green Energy and Applications (ICGEA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130186749","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}
