    Abstract

    Distributed power plants have a production capacity from a few kilowatts to 10 megawatts, which are used to generate electrical energy in places close to consumers, and their types can be solar cells, batteries fuel, micro turbines, wind power plants and pointed out If these power plants are connected to the network, they will have various effects on the network, including reducing network losses, improving the voltage profile, and increasing the reliability of the network. The lack of proper placement of scattered generation power plants in the network causes an increase in losses and an increase in energy production and transmission costs, so it is necessary to place these power plants in the network with optimization methods; In this way, the number of distributed generation power plants, their installation location and their capacity are determined in such a way that the greatest reduction of network losses occurs taking into account the constraints of the problem. In this thesis, the firefly algorithm method is used in the optimization of the problem of optimal placement of the fuel cell. After the introduction of the firefly algorithm of this method in the optimal placement of the fuel cell, a placement and load distribution program has been written and this program has been implemented and executed on the standard test networks of 30 bases and a part of the electricity distribution system of one of the gas refineries of the South Pars gas complex.

    For a better analysis of the evaluation results, the system load change index is presented as a percentage of the total system load in the places where the fuel cell is installed, which shows the efficiency of the firefly algorithm in facing this It shows the transformations.

    It should be mentioned that the data required for programming the load distribution and simulating the mentioned systems has been implemented using the Matlab program and the Psat toolbox.

    Homer software has been used for the economic analysis of the use of the fuel cell set to provide electric power and its performance has been compared with the diesel generator in the gas refinery.

    Overview of renewable energies

    Introduction

    The access of developing countries to new types of energy sources is of fundamental importance for their economic development and new studies have shown that between the level The development of a country and its energy consumption have a direct relationship. Due to the limited energy reserves in the current world, it is no longer possible to rely on the existing energy sources.

    In our country, due to the increasing need for energy sources and the decrease of fossil energy sources, it is necessary to keep the environment healthy, reduce air pollution, limit electricity supply and supply fuel to remote areas and villages. The use of new energies such as: wind energy, solar energy, hydrogen and energies inside the earth can have a special place [1].

    Today, political and economic crises and issues such as the limitation of the durability of fossil reserves, environmental concerns, population congestion, economic growth and the consumption rate, are all included in the world's topics, which with all the wide range, think of thinkers in finding suitable solutions to solve the energy problems in the world, especially ecological crises. The environment has been busy.  It is obvious that the economic and political support of countries today depends on their productivity from fossil resources, and the depletion of fossil resources is not only a threat to the economy of exporting countries, but also a major concern for the economic system of importing nations. Owners of fossil resources should be realistic that their extraction of fossil resources today requires less productivity tomorrow and ultimately, the depletion of their resources will be less in time. Fortunately, most of the countries of the world have realized the importance and role of different energy sources, especially renewable (new) energy in meeting current and future needs, and widely, in the development of the exploitation of these resources, they are still doing extensive research and fundamental investments. Considering such basic and increasing trends in the field of renewable energy use and related technologies in industrialized and developing countries in Iran, it is necessary to develop fundamental and fundamental strategies and programs.According to such basic and increasing trends in the field of renewable energy use and related technologies in industrialized and developing countries in Iran, it is also necessary to develop basic and basic strategies and programs [2].

    The global trend of paying attention to the use of renewable energy and environmental consequences has required that many organizations and centers in Iran are interested in implementing projects in this field, although this type of activity are necessary and effective, but are these measures carried out according to planning and fundamental researches at the national level or are they implemented passively and sporadically, independent delegation and taste, so that many challenges and questions still remain unanswered in justifying and defending the development of the use of renewable energies in Iran. It is obvious that this kind of development process will not be correct and sustainable without a comprehensive and modern plan. Developing a comprehensive strategy for better energy efficiency in the country requires a complete understanding of the current situation and an accurate determination of its optimal situation in the whole world. And to the ambiguities and important questions such as:

    The level of potential of each of the renewable energy carriers in Iran

    Identification and selection of suitable areas (site search)

    Codified vision for the future of renewable energy in Iran

    Economic justification according to various factors The proposal

    Planning, the method and capacity of investment, recognizing the priority for each of the renewable energies

    A codified program for the development of related technology in Iran

    Capacity and ability to be substitute and responsive

    Importance of the topic

    Today, the consequences of human intervention in the environment have been manifested more than ever. The concept of development is synonymous with the protection of the natural environment and the environment, and in the economic indicators of national accounts, such as the gross domestic product, consideration of natural and environmental resources is also mentioned. Currently, the world's energy consumption is 10 (equivalent to 10 billion tons of crude oil per year) and it is expected to increase. These figures in a few years will reach 12 and 14 figures, respectively, showing that the world's energy consumption in the next century will be huge, and of course, this important question is whether these fossil energy sources will meet the world's energy needs for survival, evolution and development in the next century. At least for three main reasons, the answer to this question is negative and new sources of energy should be replaced by old sources. These reasons include: the limitation and, at the same time, the quality of fossil energies, which logically have better applications than combustion, as well as environmental issues and problems, so that today maintaining the health of the atmosphere is considered one of the most important preconditions for sustainable global economic development.

    The pollutants caused by combustion and the increase in the concentration of carbon dioxide in the atmosphere and its consequences have made the world face irreversible and threatening changes. Global temperature increase, climate change, sea level rise and finally, the intensification of international conflicts are among these consequences. On the other hand, the imminent depletion of fossil resources and the prediction of price increases encourage policymakers to propose standards and policies for environmental control and researchers to develop less polluting and renewable resources that have the potential to replace the current energy system.

    All renewable energies are taking on a greater share in the world's energy supply system day by day. These resources promise the possibility of simultaneously responding to both basic problems of fossil resources. Renewable energies are basically compatible with nature and do not pollute, and because they are renewable, there is no end to them
