研究目的
To extract issues significant to valuing electricity from small photovoltaic systems using quantitative content analysis in four states in Australia.
研究成果
The study successfully extracted the issue of valuing the electricity from PV generation by using quantitative content analysis in four states in Australia. The results showed that avoided wholesale costs was afforded the highest priority by the stakeholders in all states. Furthermore, the significant issue was extracted by the Jaccard index, reflecting the regional characteristics such as the local energy policies or electric markets.
研究不足
The potential bias in the results due to the percentage of each type of stakeholder submission was not completely eliminated. The study focused on four states in Australia, which may limit the generalizability of the results to other regions.
1：Experimental Design and Method Selection:
The study used quantitative content analysis to identify issues significant for the estimation of the value of electricity from PV generated electricity. Five sets (A1–A5) were defined to include the various components of PV value estimation.
2：Sample Selection and Data Sources:
The study was conducted in four states in Australia: New South Wales, South Australia, Queensland, and Victoria. The data source was 291 submissions available in the website of economic regulators in each state.
3：List of Experimental Equipment and Materials:
Open source software KH coder was used for calculating the Jaccard index.
4：Experimental Procedures and Operational Workflow:
The study involved defining sets to include various components of PV value estimation, identifying the significant set based on the frequency of its elements in the submissions, and sorting the words by the Jaccard index between the set and each word.
5：Data Analysis Methods:
The Jaccard index was used to quantify the co-occurrence of the words in the submissions.
