“…Therefore, their efficiency will be higher than the fixed systems. The annual production of such systems is higher by 15-30% than the fixed tilt angle systems [18], [19]. Their shapes look more modern, and some companies have turned them into something of unique architecture.…”

Theoretical <span lang="EN-US">calculations and online system simulations using PVWatts and global solar atlas simulators, were conducted in this study to find the difference in solar power production between fixed solar power systems and tracking systems at Basra Governorate. The research included the analysis of geographical location and weather conditions and their effect on output power. The reliant power resource types and power generation of the southern region of Iraq as well as load demands were demonstrated and discussed in this research. Furthermore, the sun path, solar angles and solar radiations were considered in this study, in addition to the mathematical calculations of optimum tilt angles. The methodology used in this study was based upon theoretical and online measures of real-time weather factors, solar angles, solar radiations and model properties of the examined system. The results and factors of different systems including: peak sun hours per day, dc to ac derate factors, tilt angles, solar radiations and power production were compared to multiple similar research elements that were accomplished around the same region and some other countries. The study concluded that solar tracking system absorbs more radiations and produces an annual production of 15–30% higher than fixed tilt angle system.</span>

“…Meanwhile, with a stable high-temperature range and a number of 2,000 to 2,500 hours of sunshine annually, the Southern, Highlands, and South-central regions appear to be the best areas to enlarge the application of solar energy. These regions possess a value of daily GHI between 4 and 5.5 kWh/m 2 , which can be compared with developed solar markets in Asia [11]. Table 2 shows each region's potential in the growth of solar energy, especially for the utility-scale solar photovoltaic systems.…”

“…Vietnam is situated in the northern hemisphere, so as a general rule, the most suitable orientation of the PV array is considered to be the geographic south, which is the direction toward the Southern Pole, because the solar panels can receive most of the direct sunlight throughout the day at this orientation [11]. For average optimum tilt angle, it is recommended that solar systems should be placed with a tilt angle equal to the latitude of the placing area and face the south.…”

Vietnam has been regarded as a country with immense opportunities for renewable energy in general and for the development of solar and wind power in particular. Existing policy targets and mechanisms have been taken into practice with an aim to encourage this promising field and increase the proportion of electricity generated from these two power sources. However, the potential of these technologies has yet to be fully utilized, with approximately seven percentage of the nation's energy mix coming from renewable energy sources, according to Vietnam Electricity annual report. Conventional energy sources (coal, natural gas, and hydropower) still play a significant role in Vietnam's total primary energy supply. In this research, evaluation of the potential of renewable energy sources, emphasizing on solar power energy with its opportunities and challenges in Vietnam's power energy sector will be discussed. The main idea of this paper is to provide an overview of methodologies used for assessing photovoltaic potential and estimation of energy production from a given photovoltaic installation site. This can be a recommendation information of input indicators for investors, planners, and developers to strategize further decisions for the expansion of renewable power energy sources, especially photovoltaic systems in the chosen region.

As a rapidly developing country, Vietnam will witness a substantial growth in electricity demand in the coming decades. The surging demand will exert a huge pressure on the power transmission grid in the country. Therefore, this paper fully examines the challenges and opportunities for the power transmission grid of Vietnam. Firstly, the historical evolution and the prospected changes were reviewed, in terms of the energy demand, the production capacity, and the split in energy sources. Next, the current constraints on the power transmission grid were identified, which are related to the history and geography of Vietnam. On this basis, the authors expected that coal-fired energy production will increase in the short term, due to the rising energy demand and the limited new hydropower resources. Finally, several suggestions were put forward to improve the power transmission grid in Vietnam, namely, developing renewable energy sources, upgrading HVAC to HVDC lines, introducing MVDC links if conditions permit. The research provides a reference for the future development of the energy sector in Vietnam.
