Using Machine Learning Methods to Determine Extreme Weather-Related Outage Scenarios for Optimal Siting and Sizing of Distributed Generation and Energy Storage Facilities to Enhance Distribution Network Resiliencey
, M.Sc. Thesis Sharif University of Technology ; Hosseini, Hamid (Supervisor)
Abstract
Natural disasters such as storms, earthquakes, floods, etc. are among the factors that can damage the elements of the power grid and cause them to leave the grid. The result of these outages will be a widespread power outage, which will create many economic and social problems. Therefore, in recent years, the concept of resiliencey has been introduced in power system studies, which examines the extensive outputs in the network as a result of natural disasters.One way to improve the power system resiliency is to strengthen the network by upgrading existing equipment, installing new equipment, and modifying the operation of the network. Among these, the installation of distributed generation...
Equipment Hardening Strategies to Improve Electric Distribution System Resilience Against Wildfire
, M.Sc. Thesis Sharif University of Technology ; Vakilian, Mehdi (Supervisor)
Abstract
The severe wildfires in California, Australia, Canada, and Iran have interrupted the power system operation, caused multiple blackouts, took many lives, and caused damages to power grid infrastructure to the extent of millions and billions of dollars. Most of the recent wildfires occur in the distribution system. Therefore, enhancing power system distribution resilience against wildfire is crucial.To this end, two groups of measures are proposed: the hardening of the power network and the operational measures. The past published papers mainly studied the resilience enhancement strategies against wildfire from an operational perspective. There is a considerable gap between the past works...
Co-Planning of Transmission Expansion Planning and Distributed Energy Resources Considering Power System Resiliency
, Ph.D. Dissertation Sharif University of Technology ; Hosseini, Hamid (Supervisor)
Abstract
The loads in power systems are increasing mainly due to the development of new technologies, population growth, and the arrival of new consumers. This load growth necessitates the planning for expansion of power systems to meet the future load. Transmission expansion planning (TEP) is one of the main power system planning studies that is performed to meet the future load with an acceptable reliability level. On the other hand, in recent years, the integration of distributed energy resources (DERs) into power systems is growing, mainly driven by energy policies and the associated incentives. The impact of the growing integration of DERs into power grids on distribution network planning is...
Hardening Strategies for Enhancing the Resilience of Electrical Distribution Networks against Earthquake
, M.Sc. Thesis Sharif University of Technology ; Vakilian, Mehdi (Supervisor)
Abstract
During natural disasters, especially an earthquake the distribution systems operation is severely affected and interrupted by facing many failures. More than 80% of these outages are due to failures in distribution Systems. Therefore, it is crucial to enhance the resilience of the distribution systems (DSs) against these disasters. However, nowadays, due to limitation of resources for investment in these networks, only the most efficient measures should be implemented. In this work, studying the recent earthquakes in different countries, we have tried to identify the fundamental causes of failure of important network equipment, including distribution substations equipment and network...
Electrical Distribution System Planning in Multi-Microgrid Framework
, M.Sc. Thesis Sharif University of Technology ; Ehsan, Mehdi (Supervisor) ; Farzin, Hossein (Co-Supervisor)
Abstract
Remote-controlled switches (RCSs) have the ability to quickly isolate the faulted area from other parts of distribution systems. On the other hand, the distributed generation resources (DGs) and tie lines can supply the interrupted loads after fault occurrence as a microgrid. In this regard, this thesis proposes a planning model for simultaneous placement of RCSs, DGs, and tie lines in distribution systems with complex topologies to improve their reliability and resiliency. Presence of renewable DGs (RDGs) including photovoltaic cells (PVs) and wind turbines (WTs), as well as the uncertainties of loads, RDGs, and outage duration of the faulted areas are also considered in the proposed...
Enhancing power system resilience through hierarchical outage management in multi-microgrids

Abstract
This paper proposes a hierarchical outage management scheme to enhance the resilience of a smart distribution system comprised of multi-microgrids against unexpected disaster events. In this regard, after identifying the main features and requirements for a resilient outage management scheme, an appropriate framework is devised and the roles and tasks of different management entities in a multi-microgrids system are introduced. Based on this framework, the microgrids schedule their available resources in the first stage using a novel model predictive control-based algorithm. In the second stage, distribution system operator coordinates the possible power transfers among the microgrids and...
Electrical power system resilience assessment: a comprehensive approach

Abstract
Extreme weather events such as earthquake and hurricane have disastrous consequences on power systems. Due to the inherent nature of these events, as high-impact low-probability (HILP) events, selection of an appropriate method that can provide the effects of weather conditions on the power system behavior still remains a significant challenge. Resilience is a new concept that focuses on mitigating the destructive effects of such disastrous events on power systems. This article provides a fundamental framework for quantifying and modeling of power systems resilience, with focus on high wind incidence. The algorithm composes of four steps. In the first step, the prerequisites of the analysis...
