Simultaneous determination of location and capacity of combined wind, solar and energy storage systems in distribution networks equipped with island operation capability with the aim of improving reliability

Abstract

Distribution networks have low reliability due to the special physical structure, including radiality and low quality of the equipment used in it. On the other hand, due to the competitiveness of the electricity market and the desire of energy producers to make more profit, usually the operation of the power system, especially in distribution networks, is close to their nominal capacity. Therefore, designing distribution networks with reliability, convenience and the least possible losses has become very important. On the other hand, with the significant growth of the load and the numerous restrictions on the use of fossil energy sources, the tendency to use units of distributed generation (DG) sources has increased more than before. Renewable distributed generation sources are one of the types of distributed generation sources that have received a lot of attention today due to the lack of environmental pollution and the lack of fuel costs.

Installing adequate capacity of distributed renewable generation units and energy storage systems in suitable locations of the distribution network can significantly reduce the probability of load interruption in island operation mode and reduce system energy loss in network connection mode. . It has also been observed that the TLBO algorithm achieves the response in less time than the PSO algorithm.
