Performance-sharing optimization by risk-constrained equity investors

solution of security constrained unit commitment problem by a new multi-objective optimization method

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...

Should Investors Trust Equity Analysts?

This paper studies the holistic issue of the combination of analyst projection accuracy, diversity, and distribution. It first tracks the earnings per share and sales projections of a number of equity analysts for 17 representative U.S. companies using data from 1978 to 2012. It also compares the analysts’ consensus of earnings per share, sales, rating, and price target zone to identify the deg...

Crosstalk-Constrained Performance Optimization by Using Wire Sizing and Perturbation

In this paper, we propose a unified wire sizing and perturbation algorithm for crosstalk-constrained performance optimization that is applicable to general routing structures. Our algorithm is based on a two-stage iterative technique: we first perturb all wires to the positions with the minimum delay, then we adjust the wire sizes to further optimize delay under crosstalk constraints. The unifi...

Solving Security Constrained Unit Commitment by Particle Swarm Optimization

The issue of unit commitment is one of the most important economic plans in power system. In modern and traditional power systems, in addition to being economical of the planning, the issue of security in unit operation is also of great importance. Hence power system operation confronts units’ participation and input considering network security constrains. The issue of units’ participation is ...
