Morteza Alizadeh; Hossein Askarian Abyaneh; Alireza Bakhshai; Naser Khodabakhshi Javinani

Volume 5, Issue 2 , June 2022, Pages 123-132

http://dx.doi.org/10.22111/ieco.2022.41076.1403

Abstract
  This paper applies a new state feedback control to a distributed secondary voltage and frequency control in an islanded microgrid. The problem is focused on the output consensus of the multi-agent systems, which is converted to a first-order dynamic system. The inverter-based distributed generations ...  Read More

Leader-Follower Formation Control of Uncertain USV Networks under Stochastic Disturbances

Ali Azarbahram; Naser Pariz; Mohammad Bagher Naghibi-Sistani; Reihaneh Kardehi Moghaddam

Volume 5, Issue 2 , June 2022, Pages 133-142

http://dx.doi.org/10.22111/ieco.2022.37987.1346

Abstract
  The robust adaptive leader-follower formation control of uncertain unmanned surface vehicles (USVs) subject to stochastic environmental loads is investigated in this paper. The stochastic additive noises are included in the kinematics which stands for the un-modeled dynamics and uncertainty. The disturbances ...  Read More

Hassan Zare; Hossein Asgharpour-Alamdari; Alireza Nateghi; Mohsen Latifi

Volume 5, Issue 2 , June 2022, Pages 143-151

http://dx.doi.org/10.22111/ieco.2022.40218.1385

Abstract
  Providing purified water in marine and domestic applications, especially in remote areas regarding fossil fuels environmental pollutants, makes it hard to use conventional energy sources. Therefore, the present research seeks to construct a water purification system by using reverse osmosis technology ...  Read More

New Enhanced Droop Controller for Seamless Load Sharing in AC Microgrids in Presence of Wind Turbine and Photovoltaic Source

Sadegh Shajari; Reza Keypour

Volume 5, Issue 2 , June 2022, Pages 153-165

http://dx.doi.org/10.22111/ieco.2022.39943.1380

Abstract
  Load sharing, as an important challenge in microgrids (MGs), is realized commonly via a droop control method. Conventional droop control methods are not applicable in unpredictable renewable energy sources (RESs) like photovoltaic (PV) and wind turbines (WT) because their output power depends on the ...  Read More

An Electrical Energy Regeneration Scheme for Energy Harvesting From a Vibration Absorption System in Tall Buildings

Amir Abolmasoumi; Seyed Mohamad Ali Beladi Pour; Mahdi Soleymani; Mazdak Ebadi

Volume 5, Issue 2 , June 2022, Pages 167-176

http://dx.doi.org/10.22111/ieco.2022.41487.1412

Abstract
  Electrical energy regeneration and storage in a tall structure with the installed passive pendulum tuned mass and damper (PPTMD) is investigated. While the passive vibration absorbing system works as an energy harvesting device, an electrical system including an electric motor, power electronic converters, ...  Read More

Design a PLL for Fractional Frequency Synthesizers using DDSM with Reduced Hardware

Leila Jahanpanah; Seyed Ali Sadatnoori; Iman Chaharmahali

Volume 5, Issue 2 , June 2022, Pages 177-187

http://dx.doi.org/10.22111/ieco.2022.41006.1402

Abstract
  Phase locked loop (PLL) circuits are widely used in fractional frequency synthesizers. In these synthesizers, fractional multiples of the reference frequency can be synthesized, so the reference frequency and the bandwidth of the loop can be increased. This frequency synthesizer is commonly used due ...  Read More

Adaptive Delay Compensator Based H_2/H_∞ Wide-Area Controller to Improve the Damping of Inter-Area Oscillations

Esmaeel Rokrok; Saman Dehghaninejad; Amir Hossein Poursaeed

Volume 5, Issue 2 , June 2022, Pages 189-204

http://dx.doi.org/10.22111/ieco.2022.40754.1397

Abstract
  Recent technical advances in Wide-Area Measurement Systems (WAMS) have made it possible to use a combination of measured signals from remote locations to design centralized control. However, the transmission delay of remote signals and changes in the power system operating point are significant issues ...  Read More
