摘要： This paper presents the utilization of hardware description language VHDL-AMS (Very High-Speed Integrated Circuit plus Hardware Description Language that includes analog and mixed-signal extensions) for modeling and simulation a grid-tied 21.0 kWp real solar power plant, admitted as case study. The case study used in this research consists of a photovoltaic power system with the following features: 1) It has 90 panels of 255 Wp and 3 SMA On Grid inverters, 2) It operates without batteries, and 3) It has a dynamic power controller, called Circuitor (CDP-0), to guarantee zero injection into the grid. The main contribution of this work is modeling and simulation of a grid-tied real solar power plant, using the VHDL-AMS language (with the support of software SystemVision?), in order to develop a simulating tool capable to find the real electrical energy generation in a photovoltaic system, considering the monthly averaged direct normal radiation and the solar panel characteristics. This paper aims to present the first major developments for the future construction of a bigger VHDL-AMS tool that will allow the simulation of photovoltaic power systems, operating in a synergic way with hydroelectric power plants previously built, with the aim of optimize the coordinated operation between hydropower and solar energy, for periods of rain and hydrological drought.

[IEEE 2018 10th International Conference on Information Technology and Electrical Engineering (ICITEE) - Bali, Indonesia (2018.7.24-2018.7.26)] 2018 10th International Conference on Information Technology and Electrical Engineering (ICITEE) - Analysis of Solar Power as an Alternative Electrical Supply for the Oil and Gas Field Development
摘要： The selection of power plants in the upstream oil and gas business is highly dependent on the availability of gas from its own production, to be used as a power source for its own exploration process. Oil and gas working areas, mostly located in remote areas are very far from the power grids, hence the employment of diesel power plants are often chosen as the power supply. This study investigates solar power generation as an alternative of electricity supply in upstream oil and gas field by utilizing empty open space in the area of oil and gas well as the location where the solar panel is installed. With project scenarios following the development plans or drilling of oil and gas wells, we found that the development of solar power plants could provide greater revenue/benefits to the Production Sharing Contractors and the Government, rather than using diesel engine and hybrid power plants.

[IEEE 2018 IEEE PES/IAS PowerAfrica - Cape Town, South Africa (2018.6.28-2018.6.29)] 2018 IEEE PES/IAS PowerAfrica - Design of Photo Voltaic (PV) Solar Power Plant to Supply Electricity and to Pump Water to Chele Community
摘要： Most people in Angola are still having problems with accessing electricity and water for daily basis. In Angola only 15% of villages are having electricity and water supply. Along the years the uses of non-renewable energies have been the most used and now they are becoming difficult to access. The challenge is to transmit electricity to village because of grid costs and long distances. Renewable energy sources are a good option because require complicated infrastructure nor a national grid. Chele is a village that is in Cabinda (Angola) and situated more than 100 Km away from Cabinda city. People of Chele community have been experiencing lack of water and electricity supply, and the villagers need to walk more than 8 Km to get water. The lack of electricity in this village is due to the fact that there is no closest national grid to supply electricity and to pump water. The paper reports on a project of providing affordable and sustained electricity and water supply to Chele community. The best way to implement this is to design stand-alone PV Solar Power Plant system to supply Electricity and Pump water to Chele community.

Solar and climatic high performance factors for the placement of solar power plants in Argentina Andes sites. Comparison with African and Asian sites.
摘要： The installation of solar power plants is currently having a notable expansion. The results presented show that the Argentinean Andes range, from the central to northern latitudes, is an excellent region for the placement of these plants, due to the sum of different positive factors: very high mean annual solar irradiation, low ambient temperature and relative humidity, low precipitable water content, normal wind speeds and extremely low aerosol content of the atmosphere. The proposed regions are nearby San Antonio de los Cobres and El Leoncito, and are compared with two important locations where large solar power plants have been (or will be) built: a site in Africa (Ouarzazate, Morocco) and one in Asia (Dubai, Arab Emirates). We present results of the possible production of electricity, supplying a total of about 21000 GWh, which is 15.6% of the 2015 Argentinean electric consumption and, consequently, could reduce the emission of greenhouse gases in a total mass of 11.2 million tons of CO2eq. The installation of this type of renewable power plants, will contribute significantly to the Argentinean population due to frequent (mainly summer) cutoff of electric power supply and, in particular, to isolated (low income) populations leaving in the Argentinean Andes range.

[IEEE 2018 2nd International Conference on Smart Grid and Smart Cities (ICSGSC) - Kuala Lumpur, Malaysia (2018.8.12-2018.8.14)] 2018 2nd International Conference on Smart Grid and Smart Cities (ICSGSC) - Research of Voltage Stability in 10 kV Distribution Networks during Integrating the 2 MW Solar Power Plant
摘要： In Kazakhstan, a number of measures have been taken to stimulate the introduction of renewable energy, one of which is solar energy [1], [2]. Until 2025, the introduction of solar power plants (SPP) will be 650 MW. When integrating solar panels with inverter coupling into electrical networks, a number of difficulties arise related to the stability of the voltage in transient modes. The converter voltage inverters do not have feedback from the voltage of the external power supply system. Power generation of SPP, as a rule, is only a function of solar radiation and does not depend on the network parameters [3]. In this regard, the actual issue is the introduction of adaptive controllers for controlling inverters, depending on the change in the mode parameters [4], [5]. In this paper, we present the results of studies on the modeling of transient regimes using the example of the SPP with an installed capacity of 2 MW. The virtual model of the PSCad analyzed the stability of the voltage in the event of a short circuit on the 10 kV bus, algorithms and mechanisms for using the intelligent controller for controlling the photovoltaic system were developed.

Solar plant with short diffuser concept: Further improvement of numerical model by included influence of guide vane topology on shape and stability of gravitational vortex
摘要： An alternative renewable energy concept, i.e. the concept of a solar power plant with short diffuser (SPD), was numerically investigated by more advanced computational fluid dynamics (CFD) model. Developed model is characterized by a more sophisticated and streamlined guide vane topology. The main novelty of this work is conducted optimization of the guide vane topology, for a specific novel application related to the alternative renewable energy concept (SPD). Optimization involved determining the required guide vane topology using minimal number of geometry influencing parameters. The objective was to result in vortex genesis and stabilization with respect to the desired circumferential velocity and to minimize the required pressure potential that is necessary for stable operation of the SDP plant. Provided numerical investigation was necessary, and for sure a step forward towards consideration of the experimental plant (which will assume introduction of the turbines). It needs to be taken into account that we deal with complex flow structure that requires gradual numerical investigation, in order to be able to get detail insight in the various influences and processes that can strongly affect SPD operating parameters. The guide vane topology was altered to develop an SPD capable of establishing and maintaining a stable gravitational vortex in pressure ranges which resemble atmospheric vortex phenomena (feasible for development of a compact system, and with maximal velocities in chimney throat regions below 20 m s?1). The study outlines nine cases, each representing the altered guide vane design, where the best case is determined and compared with the available experimental data from other research groups. The comparison indicates that the numerical model, although quite simple, is accurate and robust in predicting the distribution of local velocity and pressure profiles and fit for implementation on wind turbines in order to determine the influence of the installed turbines on the vortex shape and stability in a future study. An important finding is that the swirl ratio can be manipulated by altering the guide vane shape, and it is independent of the Reynolds number (which will be important during the design phase since it can be used as a control strategy for vortex genesis and as a prevention of unintentional genesis regarding additional multiple vortices). The gained numerical results revealed specific operating conditions that will ensure a safer environment around the SPD and that will enable a carbon free electricity production.
