The optimizing that is noticed in this paper offered by presenting a sensitivity factor to reduce of annual energy loss in network and annual costs of DG. It used algorithm method in order to solve optimizing problem and also used IEEE 33-bus radial distributed network as system test. It used 288-h average load model and forward/backward sweep technique to calculate the annual energy loss. Manuscript profile -

The present study was conducted for Optimal Solar Power Station Site Selection Using the Analytical Hierarchy Process (AHP) in Iran, and the Expert Choice software. AHP is one of the most widespread multi-criteria decision-making tools. The research considered criteria and sub-criteria such as the amount of radiation, number of sunny days, mean temperature, air humidity, precipitation, amount of dust and pollution, and cloudiness factor. For obtaining the optimal location using the AHP method, implemented in Expert Choice, pairwise comparison is made between the sets for weighting after the hierarchical levels, including the goal, criteria, sub-criteria, and alternatives (intended locations), are specified. As the sets are weighted, the compatibility of judgments is analyzed, which must be less than 0.1. The capitals of the provinces of Iran were considered in the research. From among the thirty-one locations in the examined region, the city of Zahedan was selected as the best location for establishment of solar power stations, and the other alternatives were assigned the next priorities given their weights. Moreover, sensitivity analysis was made on the major criteria, and the impact of parameter weight on the alternatives was assessed. Manuscript profile -

The research’s methodology was established based on GIS spatial decision making systems. It should be mentioned that decreasing nonrenewable sources' process has been considered as one of the serious challenges. Thus, using solar energy is a solution to deal with this challenge. The high topoclimatic and physical properties of the East Azerbaijan tends to establish solar panels for producing electricity. In order to evaluate the possibility of establishing solar systems, within this research we aim to apply GIS-multi criteria decision making models for integrating the data and selecting to potential sites for solar panels. To achieve this, the prior options from different options of analyses network model (ANP) was applied for analyzing the criteria. As part of methodology, the Landsat satellite was used for extracting land use/cover. The SRTM dataset also employed for exploring the elevation, slope, aspect and solar shining. The climate dataset were used for monitoring climatological parameters such as raining, temperature, humidity, number of dusty days, number of cloudy days and sunny hours within the period of 1986 to 2014. Finally the solar panel suitability maps achieved by compounding the informative layers and multiplying those criteria were accessed from executing the model. The results indicated that 48.61% of the study area has very high suitability for solar panels programs. While the northern parts of East Azerbaijan province includes very low potentiality for producing solar based energy. Manuscript profile -

The ability of voltage source converter (VSC)-based HVDC to independently control active and reactive power is well represented by the model. The model is used to develop an OPF-based optimal location algorithm of two systems two terminal HVDC to minimize the total fuel cost and active power losses as objective function. The optimization framework is modeled as non-linear programming (NLP) and solved by Matlab and GAMS softwares. The proposed algorithm is implemented on the IEEE 14- and 30-bus test systems. The simulation results show ability of two systems two terminal HVDC in improving the power system operation. Furthermore, two systems two terminal HVDC is compared by PST and OUPFC in the power system operation from economical and technical aspects. Manuscript profile -
