In the active distribution networks (ADNs), emerging trend of high penetration sustainable energy sources such as wind turbines, photovoltaics, and forthcoming integration storage devices additional dynamic loads like plug-in-electric vehicles (PEVs) influences to change nature electric networks. Consequently, it deteriorates power quality reliability in terms unacceptable voltage rise-drop, ha...
This paper proposes a method for choosing the best coordinated expansion planning of generation and transmission systems considering an annual outage cost and a probabilistic power system reliability criterion (RLOLEGTS). The objective method minimizes a total cost which are not only an investment budget for constructing new generators and transmission lines but also an annual outage cost. Main...
In restructured power systems, generation companies should offer a power - price curve to the market operator to participate the auction. The proposed bidding curve has a considerable impact on the unit profit, especially in pay as bid markets. The optimal bidding curve depends on the final market clearing price which is uncertain in the stage of bidding. This paper proposes a novel approach f...
در سیستمهای قدرت امروزی یکی از مهمترین مسائل مانیتورینگ online سیستم بمنظور حفظ شرایط کارکرد نرمال و نزدیک کردن سیستم به شرایط کارکرد بهینه می باشد. تمامی توابع کاربردی موجود در سیستمهای مدیریت انرژی از قبیل فلوی توان بهینه (optimal power flow )، توزیع بار اقتصادی (economic dispatch ) و... داده های مورد نیاز خود را از تخمین گر حالت دریافت می کنند. به بیان دیگر تخمین گر حالت را می توان به عنوان ...
The increasing penetration of renewable energy results in changing the traditional power system planning and operation tools. As the generated power by the renewable energy resources are probabilistically changed, the certain power system analysis tolls cannot be applied in this case. Probabilistic optimal power flow is one of the most useful tools regarding the power system analysis in presen...
Uncertainty analysis of voltage in distribution system is the main feature of current study. This paper presents a probabilistic analysis of radial distribution networks considering wind power resources. The wind turbines are modeled as probability distribution functions. Also, the loads are modeled with Gaussian and gamma distributions. Monte Carlo simulation is used for the probabilistic load...
