Reliable and efficient operation of distribution network by connecting solar distributed generation

Abstract

One of the major issues in the distribution network (DN) is ensuring that power systems operate optimally in light of the effects of distributed generation (DG). In a broader sense, optimal operation in a power system refers to the most efficient use of all active and reactive power generation and control equipment that adheres to physical and technical constraints. Most studies focused on DG size and location in the DN, using various optimization techniques for loss reduction. But in a practical distribution network, reliable operation is dependent on the demand and power supply at any given moment. Solar DGs provide variable power throughout the day, and loads are similarly variable. It is difficult for the DN to function efficiently and reliably while handling variable loads and DG power supplies. Voltages and power losses are measured as loads change by connecting solar DGs to assess the performance of the DN.

Comparative analysis of single-axis solar tracker performance with and without reflector under various weather conditions

“…Solar panels, one of the main parts used in SPPs, have the ability to directly convert solar radiation into electricity [6]. The relatively low efficiency of solar panels is still evident [7]. The significant obstacle posed by the limited efficiency of solar panels necessitates the implementation of a system to enhance their efficiency [8].…”

Optimal load management of autonomous power systems in conditions of water shortage

“…The use of energy storage can extend the period of "clean" electricity use during the day and further reduce diesel consumption, as well as improve overall system reliability. As the cost of energy storage decreases in the future, it will increasingly be used in isolated power systems, reducing dependence on imported energy resources [7]- [10].…”

“…In particular, this is due to the fact that the operation of autonomous power systems with a high degree of renewable energy sources can create significant system balancing problems. As a consequence, from the point of view of cost minimization, decentralized integration of renewable energy sources on the basis of Smart grid and Microgrid smart energy systems is currently seen as the most promising way to improve the stability and reliability of such systems [7]- [10].…”
