Coordination between the central control unit and local control function of a photovoltaic system under the uncertainties of sunlight and three‐phase unbalanced loads

open access: yesIET Renewable Power Generation, 2021
At present, high penetration of photovoltaic (PV) systems on low voltage (LV) distribution systems is increasing worldwide because of several favourable conditions, such as government policies, decreasing cost of PV technologies, and environmental ...

Distributed Risk-Limiting Load Restoration in Unbalanced Distribution Systems With Networked Microgrids [PDF]

open access: yesIEEE Transactions on Smart Grid, 2020
To enhance the resilience of distribution systems (DSs), networked microgrids (MGs) can be employed to restore critical loads after a blackout. However, uncertainties of renewable energy sources (RESs) and loads bring challenges to load restoration.

An Alternate Representation of the Vector of Apparent Power and Unbalanced Power in Three-Phase Electrical Systems

open access: yesApplied Sciences, 2020
Low-voltage distribution systems are typically unbalanced. These inefficiencies cause unbalanced powers that can significantly increase the apparent power of the system.

Distributed Load Restoration in Unbalanced Active Distribution Systems

open access: yesIEEE Transactions on Smart Grid, 2019
The resilience of modern power systems has been constantly threatened by various natural disasters and man-made attacks. Under those threats, fast and automatic restoration actions are critical for restoring impacted systems to normal operating conditions and preventing from additional disastrous consequences.

Distribution System Restructuring: Distribution LMP via Unbalanced ACOPF

open access: yesIEEE Transactions on Smart Grid, 2018
The emerging distribution system with a proliferation of distributed energy resources and flexible demand assets is expected to experience a restructuring process, just as what has been happening in the transmission system. This paper introduces the distribution locational marginal price (DLMP) as an effectively economic signal to quantify marginal ...

Optimal dispatch of PV inverters in unbalanced distribution systems using Reinforcement Learning [PDF]

open access: yes, 2022
In this paper, a Reinforcement Learning (RL)-based approach to optimally dispatch PV inverters in unbalanced distribution systems is presented. The proposed approach exploits a decentralized architecture in which PV inverters are operated by agents that ...

Multi-objective Evolutionary Algorithms for Power Distribution System Optimal Reconfiguration

open access: yesCLEI Electronic Journal, 2019
In this paper two reconfiguration methodologies for three-phase electric power distribution systems based on multi-objective optimization algorithms are developed in order to simultaneously optimize two objective functions, (1) power losses and (2) three-
