[IEEE 2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia) - Singapore (2018.5.22-2018.5.25)] 2018 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia) - Spatial Data-Based Techno-economic Evaluation of Solar Hydrogen Production in the Middle East and North Africa (MENA) Region
摘要： The Middle East and North Africa (MENA) region is endowed with solar energy that can be harvested and stored as hydrogen, which has gained increasing focus as a secondary energy medium. This paper introduces modeling and feasibility analysis of cost-optimized hydrogen production, storage, shipment, and methanation in the MENA region. The analysis is based on the economic modeling of hydrogen production through the combination of photovoltaic solar power and electrolysis systems, utilizing NASA surface Meteorology and Solar Energy database (2010)[1]. A system of 100MW grid-connected photovoltaic PV power plant (grid-PV) in combination with hydrogen producing electrolyzer are simulated using spatial data for the MENA region. Then, the simulation assesses cost of methane production by Sabatier synthesis of carbon dioxide. The unit cost of hydrogen from a system, which consists of 100MW PV solar plant and electrolyzer, ranged 4-8 US$/kg. Methanation was found to be expensive vis-à-vis regionally traded natural gas. Location is a major determinant to hydrogen cost due to the difference in irradiation and logistics. In conclusion, this paper can serve as an atlas for mapping the cost of solar power and hydrogen production in the MENA region, and facilitates further research in the future.

[Energy, Environment, and Sustainability] Advances in Solar Energy Research || Techno-Economic Potential of Large-Scale Solar Deployment in the US
摘要： PV system generates electricity with minimum environmental impact reduces than conventional greenhouse gas emission and consequently reduces the effects of global warming. In late of 2014, the Indian government announced an ambitious target of 100 GW installation capacity of solar PV systems by 2022. Since then, India has achieved notable progress towards this goal and has installed 20 GW cumulative solar capacity with 9.6 GW in 2017 alone. Based on the 2015 MIT Energy Initiative, by 2050, a major fraction of the world’s electric power will come from solar sources. However, this poses many technical and economic challenges on the electrical infrastructure. In this chapter, we focus on the US case, by studying the technical and economic potentials of large-scale deployment of the most commonly recognized types of solar; photovoltiac (PV) and concentrated solar power (CSP) at different locations in the US. The technical potential is assessed based on grid interconnection topologies, and solar system performance. The economic potential is evaluated based on several metrics such as the levelized avoided cost of energy (LACE) and levelized cost of electricity (LCOE), and the possibility of integration into the electricity markets. The economic potential also covers the subsidies, taxes, policies, and incentives for large-scale solar deployment. Two simulation case studies are implemented on two large-scale solar PV and CSP projects at different locations in the US to evaluate their techno-economic potentials.

Research on Grid Parity Predictions of Centralized Photovoltaic Electricity
摘要： Over the past decade, the photovoltaic (PV) industry in China has made great progress. However, this progress benefited from a series of subsidy policies, and with the continuous enlargement of the scale of centralized PV (CPV), the large subsidies have created great pressure on government finance, so achieving grid parity in CPV electricity is an urgent matter. This paper studies the grid parity of CPV electricity. First, this paper calculates the levelized cost of energy (LCOE) of CPV electricity. Second, using historical data and a dual learning curve, the paper predicts the LCOE of CPV electricity under scenarios with different resource zones and utilization times. Third, the paper predicts the LCOE of coal-fired electricity and draws conclusions based on changes in the price of coal and charcoal. Finally, the paper predicts when grid parity in CPV electricity in different resources areas will be achieved.

In-situ performance and degradation of three different photovoltaic module technologies installed in arid climate of Morocco
摘要： This paper presents the results of a first-time study on the long-term performance, degradation and cost analysis of three different PV module technologies - monocrystalline silicon (m-Si), polycrystalline silicon (p-Si), and amorphous silicon (a-Si) - installed in the desert climate of Errachidia, Morocco. It mainly aims to determine the most adapted module technology. The performance ratio (PR), degradation rate (Rd) and levelized cost of electricity (LCOE) indicators have been determined for each installed PV technology. Results revealed that p-Si technology exhibits the best performance with the highest PR of 82.54 ± 5.84 % compared to 82.24 ± 4.77 % for m-Si and 81.36 ± 3.79 % for a-Si. However, the p-Si technology degrades faster with 0.92 ± 0.11 %/year compared to 0.45 ± 0.11 %/year for m-Si and 0.72 ± 0.11 %/year for a-Si. Thus, the generated energy and the calculated Rd of the investigated technologies are used for the LCOE calculation. Indeed, the lowest LCOE value is noticed for p-Si system with 10.32 c€/kWh compared to 11.15 c€/kWh for m-Si and 13.18 c€/kWh for a-Si.

Accelerating Photovoltaic Market Entry with Module Replacement
摘要： This work highlights an opportunity for emerging high-potential solar photovoltaic (PV) technologies to enter the market sooner than expected. PV modules are conventionally required to operate with minimal degradation for 25 years or more. We evaluate a PV system operating strategy that anticipates periodic replacement of all modules. Shorter-lived modules are later replaced with higher-performing, longer-lived modules, leading in many cases to a competitive levelized cost of electricity (LCOE).

Technical and Economic Optimal Solutions for Utility-Scale Solar Photovoltaic Parks
摘要： Solar energy has shown to be a successful renewable source, wherefore large investments are planned in the upcoming decades. This work aims at developing technical and economical solutions to optimize a utility‐scale grid connected solar photovoltaic park with an installed capacity of 24 MWp. Several successive simulations were automatically performed with the PVSyst software, so that each influencing parameter is individually analyzed. Moreover, a comprehensive study touching relevant aspects, such as central versus string inverters, landscape versus portrait dispositions, the optimal tilt angle (for fixed tilt systems), backtracking strategy (for single axis tracking systems), shading limit angle, and pitch is performed with the objective of finding the configuration leading to the higher grid injected energy output. The levelized cost of energy (LCOE) was obtained for 12 different cases in which, for both fixed tilt and single‐axis tracking (SAT), central and string inverters and portrait/landscape disposition were considered. The lowest LCOE achieved was 32.23 €/MWh, which is a clear indication of the competitiveness of the solar Photovoltaic (PV) technology. The most economic viable solution is characterized by the employment of an SAT system with the backtracking strategy, together with string inverters and module portrait disposition.

Optimal Design Method of a Hybrid CSP-PV Plant Based on Genetic Algorithm Considering the Operation Strategy
摘要： Solar energy is the most abundant renewable energy and it has a great potential for development. There are two ways to transfer solar energy to electricity: photovoltaic power generation (PV) and concentrated solar power (CSP). CSP-PV hybrid system can be fully integrated with the advantages of the two systems to achieve low cost, stable output, and manageable to generate electricity. In this paper, the operation strategy of the CSP-PV system is proposed for parabolic trough CSP system and PV system which are now commercially operated. Genetic algorithm is used to optimize the design of the system and calculate PV-installed capacity, battery capacity, and storage capacity of CSP system, making the system to achieve the lowest cost of electricity generation. The results show that the introduction of the CSP system makes it possible to ensure the stability of the output power of hybrid system when the battery capacity is small, which greatly improves the annual utilization time of the PV and reduces solar abandonment. When the system is optimized by operation characteristics of Spring Equinox, the lowest LCOE is 0.0627 $/kWh, the rated capacity of PV and CSP system are 222.462 MW and 30 MW, storage and battery are 356.562 MWh and 14.687 MWh. When the system is optimized by the operation characteristics of the whole year, the lowest LCOE is 0.0555 $/kWh, the rated capacity of PV and CSP system are 242.954 MW and 30 MW, respectively, and the capacity of heat storage and battery are 136.059 MWh and 8.977 MWh. The comparison shows that the power generation curves of the hybrid system are similar in the two optimization-based methods—Spring Equinox based and annual based, but LCOE is lower when optimized by the annual operation characteristic, and the annual utilization rate of the system is higher when optimized by Spring Equinox based.
