[ 1 ] - Optimal Reconfiguration and Capacitor Allocation in Radial Distribution Systems Using the Hybrid Shuffled Frog Leaping Algorithm in the Fuzzy Framework
In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...
[ 2 ] - Reconfiguration of distribution systems to improve reliability and reduce power losses using Imperialist Competitive Algorithm
Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...
[ 3 ] - کنترل یکپارچه ژنراتور القایی، محدودکننده جریان خطا و ذخیره‌ساز انرژی در مزارع بادی
یکی از مشکلات مهم سیستم‌های قدرت که دارای مزارع بادی با ژنراتورهای القایی دوسوتغذیه هستند قابلیت ایستادگی در مقابل خطای این ژنراتورها و نوسانات توان خروجی آنهاست. در مواقعی که این ژنراتورها توان قابل توجهی از سیستم قدرت را تأمین می‌کنند خروج آنها در هنگام خطا، باعث ناپایداری شبکه می‌شود. طبق نیازهای جدید بر اساس کدهای شبکه، در مواقع خطا که ولتاژ در پایانه ژنراتور افت می‌کند، بایستی به منظور حفظ...
[ 4 ] - A New Intelligent Controller for Parallel DC/DC Converters
In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...
[ 5 ] - Stochastic Joint Optimal Distributed Generation Scheduling and Distribution Feeder Reconfiguration of Microgrids Considering Uncertainties Modeled by Copula-Based Method
Using distributed generations (DGs) with optimal scheduling and optimal distribution feeder reconfiguration (DFR) are two aspects that can improve efficiency as well as technical and economic features of microgrids (MGs). This work presents a stochastic copula scenario-based framework to jointly carry out optimal scheduling of DGs and DFR. This framework takes into account non-dispatchable and ...
[ 6 ] - Stochastic Optimal Scheduling of Microgrids Considering Demand Response and Commercial Parking Lot by AUGMECON Method
Regarding the advances in technology and anxieties around high and growing prices of fossil fuels, government incentives increase to produce cleaner and sustainable energy through distributed generations. This makes trends in the using microgrids which consist of electric demands and different distributed generations and energy storage systems. The optimum operation of microgrids with consideri...
[ 7 ] - Combined Heat and Power Economic Dispatch using Improved Shuffled Frog Leaping Algorithm
Recently, Combined Heat and Power (CHP) systems have been utilized increasingly in power systems. With the addition penetration of CHP-based co-generation of electricity and heat, the determination of economic dispatch of power and heat becomes a more complex and challenging issue. The optimal operation of CHP-based systems is inherently a nonlinear and non-convex optimization problem with a lo...
