The proposed circuit is able to operate for both symmetrical and asymmetric inverter, which can be used for fuel cell and photovoltaic systems. The magnitude of two dc sources in basic module can be adopted for symmetrical and asymmetrical structure. In the symmetrical multilevel inverter, the magnitude of dc source is identical for each module. However, the magnitude of dc source for basic modules is unequal in asymmetrical configuration and their magnitudes are achieved from binary and trinary progression. Comparison results prove that the proposed circuit requires a fewer number of components, reduced power loss and improve the efficiency of the inverter. Moreover, the total standing voltage on switches is acceptable compare to contemporary topologies. The proposed inverter can be implemented to low-medium power renewable energy systems. Simulation and experimental results for 11, 15 and 19-level inverters are analysed to validate the operation and performance of proposed topology.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"4 ","pages":"Article 100094"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47496894","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 acceleration towards decarbonization of electricity supply through renewable technologies development is critical for reducing CO<sub>2</sub> emissions. During peak-hours electricity consumption increase and peak units are needed to balance the demand and supply. Despite the technology updates done in many peak units, the most efficient fossil plants are not emission free. An approach to combine economic and environmental benefits through DR implementation was developed and applied to the Iberian Electricity Market data (MIBEL). It was developed a methodology that reduces emissions and replaces peak units with high prices by production with lower prices. The results indicate that generation portfolio and climatic conditions have a large impact on the offset emissions levels at each moment. At night polluting technologies have a greater share in the supply mix. Through DR implementation is possible to save emissions, reducing the need for peaking plants and simultaneously achieve an overall price decrease at peak hours, without compromising users’ comfort.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"4 ","pages":"Article 100093"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46098905","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 advanced Gaussian trajectory dispersion model is used to evaluate the consequent impacts of nuclear power plant (NPP) accidents with Fukushima nuclear meltdown emission levels occurring at all of the four power plants (NPP1–NPP4) in Taiwan. Our study indicates the exposure pathway emergency planning zone (EPZ) would be as far as 17, 25, 5 and 17 km downwind from NPP1 to NPP4, respectively, for an event occurring on 11 March 2011. Our study indicates that the percentages of the land in Taiwan becoming permanent evacuation zones (PEZs) are as high as 8%, 13%, 2%, and 11% for an event occurring randomly during a year from 11 March 2011 at NPP1 to NPP4, respectively. The mean percentages of the land for Taipei City becoming PEZs are 35%, 71%, 0% and 48%, respectively. The mean percentages of the land for Kaohsiung City becoming PEZ are 4%, 5%, 5% and 3%, respectively. The analysis shows that for pursuing net-zero carbon emission, the conventional nuclear energy might not be a good choice for Taiwan, since about 2–13% of the Island can be inhabited for more than 30 years while a Fukushima-level nuclear meltdown occurs. The methodology and the trajectory model used here can be applied for other countries for quantifying the EPZ and PEZ for each nuclear power plant to substitute a conventional straight-line-type plume model, such as MACCS2.</p></div>","PeriodicalId":72914,"journal":{"name":"Energy and climate change","volume":"4 ","pages":"Article 100090"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49390681","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}
