<p>In the majority of the isolated areas, the diesel generator is the principal source of electric power. For these areas, the price of extension of the electrical supply network is prohibitory and the price of fuel increases radically with insulation. The continuous fall in the prices of the generators based on renewable energy and the increasing reliability of these systems led to a greater use of the sources of renewable energy for the generation of electric power in the isolated areas. The diesel generators can incorporate in a network with other sources in base of renewable energies in order to create a new network known as distributed network. More recently intermittent renewable resources such as the wind power were considered as a distributed generation which is seen as being deployed to reduce the total emissions. The distributed generation equipment sets causing electric disturbances result in destabilizing the global network as well as pollutant, for these reason, system D-FACTS comes to answer all the concern of the customers, manufacturers, suppliers and the managers of the distributed network<em>.</em></p>

Electrical networks are evolving and taking on more challenges as the inclusion of renewable energy and distributed generation units increase, specially at distribution levels. Big trends of generating electricity with alternative and renewable resources has promoted the formation of distribution networks subsystems or micro grids, capable of supplying their own electric demand and to export energy to the interconnected system, if necessary. However, the effects of these generation units into the network and into the microgrid as well are many, as harmonic distortion, voltage flickers and especially in electrical protections.This paper provides an overview about implementation of renewable energy and distributed generation worldwide, as well as an introduction to microgrids concept and its main impacts and challenges into the electric systems. Finally, the main impacts of microgrid on protection equipments are presented at a distribution level, being adaptive protections one of the solutions to the dynamic changes of the electric system.

The Nigerian power problem resulted to incessant and erratic supply of electricity and this has destroyed many industrial processes in the country. It has reduced productivity and has increased unemployment rate in the country to over 50million (this figure is over 70% of Nigerian youths). This has led many of the youths in the country to crime. It has led to the deaths of many innocent people in the country. As of 2016, the electricity energy consumption in the world from the world fact book revealed that the average power per capita (watts per person) in the United States is 1,377 Watts. In Canada, it is 1704 Watts per person and in South Africa; it is 445 Watts per person and in Australia, average power per capita (watts per person) is as high as 1,112 Watts. Whereas, the average electricity consumed in watts per person in Nigeria is just 14 Watts.  Unfortunately, this has put the country in a rank of 189 out of 219 countries estimated. In this research work, a Hybrid Electric Power System (HEPS) which comprises Hydro Electric Power Plant (HEPP) and Diesel Generator (DG) was modelled and a control algorithm was established to improve the performance of the system. Hybrid power system mathematical and Simulink models were developed. The output power of the developed Simulink model was be optimized using optimum power point optimization techniques and control algorithms. Simulink models of the two components of the Hybrid Electric Power System were produced using MATLAB/Simulink software. The develop Simulink models was interconnected and final model was developed. The results obtained revealed that the problems associated with conventional methods of power generation was overcomed by the development of this renewable and non-renewable energy resources Hybrid Electric Power System (HEPS) models.

Indonesia is the nation with abundant of natural resources. Natural resources itself in kind of crude oil, natural gas, coal, geothermal, hydropower, wind, and biomass become the commodity which is targeted to enhance economic development by utilizing them as the object for electrical supply in Indonesia, especially for nation electricity need. In Indonesia, the index for electrification reaches up to 94.91% in 2017 and continuously increasing year by year. It is contrary to regional electrification index as some developing region still far below 80%, even though those region have a huge amount of renewable resources potential, ranging from, solar, water, biomass, wind, geothermal as well as garbage. That potential does not go in line with renewable energy power plant which counts to 1% of total energy source. It can be analyzed that it happen because the inavailability of technology and social-political activity in Indonesia. Other than that, the system of centralization of electrical provision inhibit the potential of each region that could directly handled by local society. Therefore in this paper we propose a solution in form of renewable energy cooperatives (REC). REC applies the system of people economy to enhance the power plant establishment. REC would give capital to local society that comes from their own, to establish their own power plant. This allows the shifting to decentralization to optimize region potential and help government to reach the goal of electrification in Indonesia and plays major role in transforming Indonesian economic.

In the present scenario, world is progressing in the direction of energy crisis and severe ecological concerns due to the excessive utilization of non-renewable resources. Fossil fuel reserves are inadequate and produce hazardous geological contamination throughout the energy extraction. To meet such challenges, active amalgamation of renewable energy resources (RER) with distributed generation (DG) is the only way to progressing in future. Demand response scheme and battery storage is also essential for the reliable and consistent energy generation and efficient utilization. The role of RER in the evolution of DG is presented in this paper. The objective of this paper is to evaluate the barricades, reimbursements and influence of renewable energy based DG planning and framework. Moreover, a comparative assessment of renewable DG optimization based on optimization criteria and enhanced outcomes are evaluated for this futuristic atmospheric friendly approach.

Distributed electric power generation technologies typically use little or no water per unit of electrical energy produced; in particular, renewable energy sources such as solar PV systems do not require cooling systems and present an opportunity to reduce water usage for power generation. Within the US, the fuel mix used for power generation varies regionally, and certain areas use more water for power generation than others. The need to reduce water usage for power generation is even more urgent in view of climate change uncertainties. In this paper, we present an example case within the state of Tennessee, one of the top four states in water consumption for power generation and one of the states with little or no potential for developing centralized renewable energy generations. The potential for developing PV generation within Knox County, Tennessee, is studied, along with the potential for reducing water withdrawal and consumption within the Tennessee Valley stream region. Electric power generation plants in the region are quantified for their electricity production and expected water withdrawal and consumption over one year, where electrical generation data is provided over one year and water usage is modeled based on the cooling system(s) in use. Potential solar PV electrical production is modeled based on LiDAR data and weather data for the same year. Our proposed methodology can be summarized as follows: First, the potential solar generation is compared against the local grid demand. Next, electrical generation reductions are specified that would result in a given reduction in water withdrawal and a given reduction in water consumption, and compared with the current water withdrawal and consumption rates for the existing fuel mix. The increase in solar PV development that would produce an equivalent amount of power, is determined. In this way, we consider how targeted local actions may affect the larger stream region through thoughtful energy development. This model can be applied to other regions, other types of distributed generation, and used as a framework for modeling alternative growth scenarios in power production capacity in addition to modeling adjustments to existing capacity.
