“…This work considers three system operation conditions as follows [11][12][13]; -N-0 or N condition: Normal condition (base case) represents the system with all elements in service. -N-1 condition: Single contingency event that involves the loss of a single system element (generator, transformer, transimission linr,…,etc).…”

Due to the competitive nature of the electrical market, ensuring the electrical system's secure, efficient, and cost-effective functioning is one of the most crucial challenges. This paper presents a new contingency management strategy for distribution systems to successfully deal with routine maintenance by applying the appropriate control action while taking operational requirements for voltage deviation and transmission line overloading into account. The proposed management strategy can help electricity company operators: 1) reduce generation costs by reducing the number of generators, 2) meet the required load demand with the least amount of generation consumption, and 3) ensure the system is secure so that all load lines are not loaded to their maximum power. The effectiveness of the proposed strategy is assessed using a multiple severity indices, which includes five indices. The five severity indices are real power performance index (PI), voltage deviation index (VDI), active power loss index (PLI), reactive power loss index (QLI), and line utilization factor (LUF). The proposed contingency management strategy has been implemented in MATLAB software utilizing the particle swarm optimization (PSO) technique for typical IEEE 14-bus distribution system operation considering three probable contingency cases. Case A considers the failure of a bus-containing generator. Case B considers the failure of a transmission line. Case C considers the failure of two transformers. The simulation results indicate a satisfactory range of proposed indices within safe limits.

“…The Whale Optimization Algorithm, Sine Cosine Algorithm, and Multi-Verse Optimization Algorithm have been developed as multi-objective optimization methods for identifying the optimal mix sizing and positioning RES integrated into IEEE 33-bus and 118-bus test systems, as well as a realistic portion of the Egyptian distribution network [8]. The digital model was developed using the DIgSILENT power system calculation package to simulate the Egyptian power system at 500 kV and 220 kV levels to conduct power system studies such as load flow, short circuit, fault, and stability to evaluate performance and ensure compliance with grid code technical requirements [9].…”

Modified Analytical Technique for Multi-Objective Optimal Placement of High-Level Renewable Energy Penetration Connected to Egyptian Power System

et al. 2023

The 2022 United Nations Climate Change Conference (COP27) recommended that Egypt be converted to green energy, in addition to increasing the demand for annual energy consumption, which will lead to an increase in the use of renewable energy sources (RES) in Egypt. The Egyptian Ministry of Energy and Electricity plans to build RES (photovoltaic systems and wind farms) connected to the Egyptian power system (EPS). It is a defect to choose the position and size of the RES based on only power calculations because the RES is an intermittent source. This paper presents a modified analytical energy technique for locating RES in IEEE 33-bus and 69-bus distribution networks and a realistic 25-bus 500 kV EPS. An analytical multi-objective function has been developed to determine the optimal locations of DGs or RESs based on power losses and annual energy loss calculations of the system depending on weather conditions. The efficiency and feasibility of the proposed algorithm based on the IEEE 33-bus and 69-bus distribution networks and the realistic 25-bus 500 kV EPS have been tested and compared with PSO and GA. The impact of RESs on the performance of the 25-bus 500 kV EPS has been investigated based on annual energy losses and operation stability depending on weather conditions. The results showed that the proposed technique used these effective values to obtain optimal weather-adjusted locations. The optimal locations of PV systems or wind systems based on energy calculation improved the voltage profile better than power calculation by about 2%, and the annual energy losses decreased by about 7%. The performance of the 25-bus 500 kV EPS, due to the addition of RES, resulted in a decrease in the annual energy losses of 47% and an improvement in the voltage profile and system stability.
