[ 1 ] - پخش بار اقتصادی دینامیکی – زیست محیطی مبتنی بر پیشنهاد سمت مصرف با استفاده از الگوریتم ترکیبی غذایابی باکتری و تکامل تفاضلی
یکی از وظایف اپراتور مستقل سیستم و یا اپراتور بازار، دریافت پیشنهادات سمت عرضه و تقاضا به‌منظور تعیین برنامه‌ریزی نیروگاه‌ها در سمت عرضه، برنامه‌ریزی توان مصرفی مشتریان و قیمت برق در دوره برنامه‌ریزی دربردارندة چندین بازه زمانی است. معیار اصلی اپراتور مستقل سیستم، حداکثرشدن رفاه اجتماعی بازیگران است. برای این منظور لازم است علاوه بر تابع هزینه سمت عرضه، تابع منفعت سمت مصرف نیز در تابع هدف گنجان...
[ 2 ] - MOEICA: Enhanced multi-objective optimization based on imperialist competitive algorithm
In this paper, a multi-objective enhanced imperialist competitive algorithm (MOEICA) is presented. The main structures of the original ICA are employed while some novel approaches are also developed. Other than the non-dominated sorting and crowding distance methods which are used as the main tools for comparing and ranking solutions, an auxiliary comparison approach called fuzzy possession is ...
[ 3 ] - An Intelligent Method Based on WNN for Estimating Voltage Harmonic Waveforms of Non-monitored Sensitive Loads in Distribution Network
An intelligent method based on wavelet neural network (WNN) is presented in this study to estimate voltage harmonic distortion waveforms at a non-monitored sensitive load. Voltage harmonics are considered as the main type of waveform distortion in the power quality approach. To detect and analyze voltage harmonics, it is not economical to install power quality monitors (PQMs) at all buses. The ...
[ 5 ] - Model Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation
This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...
