“…Socially, renewable energy-based industries are more labor-intensive compared to fossil fuel-based technologies because of their continued development process. Hence, the investment in the DG technologies may represent a real opportunity to meet the load growth by adopting low-cost, low-carbon, and high-efficient capacity expansion alternatives [5], [6].…”

Adding new capacity expansion alternatives using distributed generation (DG) technologies, particularly penetration of renewable energy, has several economical, and technical advantages such as the reduced system costs, the improved voltage profile, lower line loss and enhanced system's reliability. However, the DG units may lead to power quality, energy efficiency, and protection problems in the system when their penetration exceeds a particular value, generally called as the system's hosting capacity (HC) in the literature. In this paper, the HC determination of a distorted distribution system with Photovoltaic (PV)-based DG units is handled as an optimization problem by considering over and under voltage limitations of buses, current carrying capabilities of the lines, and harmonic distortion limitations as constraints. It is seen from simulation results that the HC is dramatically decreased with the increament of the load's nonlinearity level and the utility side's background voltage distortion. Accordingly, a C-type passive filter is designed to maximize the harmonic-constrained HC of the studied system while satisfying the constraints. The results indicate that higher HC level can be achieved using the proposed filter design approach compared to three conventional filter design approaches as voltage total harmonic distortion minimization, line loss minimization and power factor maximization.

Microgrids can be assumed as a solution model for green energy sources, energy storage systems, and combined heat and power (CHP) systems. In this work, the cost and emission minimization based on a demand response (DR) program is considered an optimization problem. To solve the mentioned problem a new multiobjective optimization algorithm (improved particle swarm optimization) is proposed based on a fuzzy mechanism to select the optimal value. The microgrid system includes two CHP units, fuel cell and battery systems, and the heat buffer tank. In this problem, two different feasible operating regions have been assumed in CHPs. Accordingly, to decrease the operational cost, time‐of‐use, and real‐time pricing DR programs have been simulated, and the impacts of the mentioned models are evaluated overload profiles. The effectiveness of proposed models has been applied on different cases studies by different scenarios. The proposed model solved the DR program, time of use‐DR and real‐time pricing‐DR problems. The proposed model could reduce the cost about 10%.

In this work, a novel method to plan and optimize pathways mix of urban regional energy system is proposed. A general model with vertices, paths and network balance as the elements is established, the digraph is used to describe the energy conversion and management process visually. Then, the matrices describing the characteristics of the energy network are developed. Basing on it, the objective function corresponding to the energy conversion paths is assigned as the weight, in order to make a comparison of system performance of different pathways mix. Furthermore, a case study of cogeneration system is evaluated by using the developed mathematical model. The results reveal the energy saving characteristics in different scenarios, further illustrating the applicable conditions and optimal strategies of distributed energy system. It is indicated that the proposed methodology have the ability to ameliorate energy network at the process of new-built planning and built areas reconstruction.
