The valuation of photovoltaic power generation under carbon market linkage based on real options

This paper provides a real option approach to analyze investment value for photovoltaic power generation under carbon market linkage. The primary purpose is to evaluate photovoltaic power generation under uncertainties from the perspective of power generation enterprises. Uncertainties in investment costs, electricity prices, carbon prices and subsidy payments are considered. In addition, the Market Co-movements of investment costs are considered in this study. Dunhuang is taken as a case study to evaluate the value of photovoltaic power generation through scenario analysis. The result shows that the investment value of photovoltaic power generation is negative. Enterprise should give up the investment or delay investment until mature conditions. Moreover, the investment value can be improved by technical improvement, increasing a certain range of subsidy payments, etc. The research presented would be useful for photovoltaic power generation project evaluation and related decision-marking.

Analysis of solar radiation on the surface estimated from GWNU solar radiation model with temporal resolution of satellite cloud fraction

Preliminary analysis with a solar radiation model is generally performed for photovoltaic power generation projects. Therefore, model accuracy is extremely important. The temporal and spatial resolutions used in previous studies of the Korean Peninsula were 1 km × 1 km and 1-h, respectively. However, calculating surface solar radiation at 1-h intervals does not ensure the accuracy of the geographical effects, and this parameter changes owing to atmospheric elements (clouds, aerosol, ozone, etc.). Thus, a change in temporal resolution is required. In this study, one-year (2013) analysis was conducted using Chollian geostationary meteorological satellite data from observations recorded at 15-min intervals. Observation data from the intensive solar site at Gangneung-Wonju National University (GWNU) showed that the coefficient of determination (R²), which was estimated for each month and season, increased, whereas the standard error (SE) decreased when estimated in 15-min intervals over those obtained in 1-h intervals in 2013. When compared with observational data from 22 solar sites of the Korean Meteorological Administration (KMA), R2 was 0.9 or higher on average, and over- or under-simulated sites did not exceed 3 sites. The model and 22 solar sites showed similar values of annual accumulated solar irradiation, and their annual mean was similar at 4,998 MJ m−2 (3.87 kWh m−2). These results show a difference of approximately ± 70 MJ m−2 (± 0.05 kWh m−2) from the distribution of the Korean Peninsula estimated in 1-h intervals and a higher correlation at higher temporal resolution.

Research of Quality Evaluation of PV Power Generation Project Based on the Extension Theory

In order to make a further promotion and development of photovoltaic power generation project, this paper brings the extension theory in photovoltaic power generation project quality evaluation and builds the photovoltaic power generation project extension evaluation index system and model on the basis of matter-element theory and extension analysis. Ranking the evaluating projects by calculating the indicators compared with the correlation of evaluation degrees. The paper takes three photovoltaic power generation project in Shaanxi in 2012 as an example, expounding the model is reasonable and reliable. The empirical results give a best reflection on the quality of the photovoltaic power generation project, which provide a scientific basis for project decision. The paper results provide a new thought for quality assessment of photovoltaic power generation project, enriching the photovoltaic power generation project evaluation method.

Economics Reasearch for Photovoltaic Power Generation Project Based on Different Business Model

This paper presents an in-depth economic analysis on Photovoltaic power generation (PV) project. The research is based on nine business and technical proposals which with different investment operational pattern and different distributed generation (DG) integration technology of PV project. An all-life-cycle benefit/cost (B/C) assessment methods was used to assess the feasibility of the project. Through the accurately simulate of an annual PV output and load curves from typical time, received electric power and energy balance calculations and revenue forecast results. And then different operators’ electricity price benefits based on china’s complex tariff mechanism was estimated in this paper, while the initial PV panel investment, operation and maintenance, distribution network investment and losses of PV projects were calculated. Finally, through the PI value come to the best business model. Calculation results show that if power grid enterprise as the PV power producer, and use of virtual power plant technology for DG integration means more investment value than other business mode.

Comparison of Economic Feasibility for Different Locations in Korean Photovoltaic Power Generation

This study covers the performance of a photovoltaic power generation project and an economic analysis of the project. SAM simulation tool, developed by NREL, a laboratory under DOE of USA, was used as a universal tool, and Korean weather data, electricity trading system in Korea, and Korean government incentive programs were considered. By doing so, we suggested a methodology that will be able to carry out the analysis of power generation performance and economic efficiency when photovoltaic power generation project is planned in Korea. For the weather data available four locations in Korea, the comparison of economic feasibility in photovoltaic power generation is carried out. For the best alternative location Gwangju, a city in south area of Korea, we presented a case study of a photovoltaic power generator operated in 20 megawatt grade photovoltaic power plant. We validated the suggested economic analysis methodology by analyzing the performance and economic efficiency of the Gwangju project case. The comparison analysis of economic feasibility by suggested methodology is considered to have sufficient validity, and is expected to be used in model development of photovoltaic power generation project site selection.

Study on Different Capacity of Photovoltaic Power Generation Project Compares

Development and utilization of solar and other renewable resources is the development trend on energy. Belong to one of the national industrial policy to support the strategic emerging industries to optimize the power structure, Energy conservation, environmental protection, the development of low-carbon economy has a positive effect. Different monolithic capacity of photovoltaic power generation project, in construction investment, the basic difference between the little and then be able to estimate the construction of photovoltaic power generation project investment, preliminary determination of investment projects in economic rationality.

Lessons and Challenges Encountered in the Implementation of Solar Energy – The Case of Botswana

A number of photovoltaic pilot projects have been started in Botswana since 1990. The first photovoltaic pro- ject was Manyana PV project which started in 1992. The Japanese International Cooperation Agency (JICA) PV solar pi- lot project is the most recent PV solar project in Botswana, which was launched in 2003 at Kudumatse, Motlhabaneng, and Lorolwana villages. The primary objective of all these projects was to access the viability and sustainability of solar energy technology as an alternative source of energy especially for rural based communities. Depending on the findings, such projects were also intended to be replicated in other parts of the country. Despite all these efforts by the government of Botswana and donor agencies, the level of use of PV solar systems for power generation in Botswana, particularly in isolated communities, is very low. This paper, therefore, discusses the factors that impede the rapid development of photovoltaics power generation systems in the rural environment of Botswana. The study is focused on the photovoltaic power generation project which was car- ried out in three villages in Botswana, namely Kudumatse, Lorolwana and Motlhabaneng.
