Abstract :
In recent years, the distribution network has experienced significant growth due to the increasing demand for electric energy. As a result, there is a need to expand the existing distribution network to accommodate more users. In this paper, the focus is on planning the development of electrical energy distribution networks. This involves determining the capacity and optimal location of scattered production sources and choosing the best routes for constructing new lines within the standard 33-bus distribution network. The methods used for this purpose are particle swarm optimization algorithms (PSO) and lightning search. (LSA). Simulation has been done in three scenarios. In the first scenario, the cost reduction of the network development program has been done by locating and determining the capacity of scattered production sources, and in the second scenario, this has been done by constructing new lines in the network. Finally, in the third scenario, locating and determining the optimal capacity of scattered production resources along with the construction of new feeding routes have been done simultaneously by these two algorithms. The results of the simulations indicate that the most effective method for developing electrical energy distribution networks is to simultaneously utilize distributed generation and construct new lines. In this case, network development will have the lowest cost. On the other hand, the proposed lightning search algorithm has been able to perform better than the particle swarm algorithm in all defined scenarios, and with the development program provided by this algorithm, the lowest cost has been obtained.
