A Selective Harmonic Compensation and Power Control Approach Exploiting Distributed Electronic Converters in Microgrids
(Journal article; Peer reviewed, 2019)This paper proposes an approach to obtain harmonic compensation and power control by exploiting the electronic power converters deployed in low-voltage microgrids. By the proposed approach, distributed harmonic current ... -
Accounting for reserve capacity activation when scheduling a hydropower dominated system
(Journal article; Peer reviewed, 2020)As the penetration of variable renewable power generation increases in power systems around the world, system security is challenged. It is crucial to coordinate the available flexible generating resources, such as hydropower, ... -
Clustering methods assessment for investment in zero emission neighborhoods’ energy system
(Peer reviewed; Journal article, 2020)This paper investigates the use of clustering in the context of designing the energy system of Zero Emission Neighborhoods (ZEN). ZENs are neighborhoods who aim to have net zero emissions during their lifetime. While ... -
Dynamic incorporation of nonlinearity into MILP formulation for short-term hydro scheduling
(Journal article; Peer reviewed, 2019)Optimization tools are widely used for solving the short-term hydro scheduling (STHS) problem in a cascaded hydro system. In a mixed integer linear programming (MILP)-based formulation, the nonlinear and non-convex hydropower ... -
Fundamentals and recent developments in stochastic unit commitment
(Journal article; Peer reviewed, 2019)Optimal scheduling of power generating units must take into account possibilities of forecast errors and equipment failure. The stochastic unit commitment problem addresses scheduling of generating units under uncertainty. ... -
Long-term Value of Flexibility from Flexible Assets in Building Operation
(Peer reviewed; Journal article, 2022)In this work, we investigate how flexible assets within a residential building influence the long-term impact of operation. We use a measured-peak grid tariff (MPGT) that puts a cost on the highest single-hour peak import ... -
Non-intrusive identification of hydro power plants' dynamics using control system measurements
(Peer reviewed; Journal article, 2020)In this paper we propose two non-intrusive methods for identifying hydro power plant dynamics using standard system identification techniques. The purpose of the tests is to obtain transfer functions relevant for the ... -
Scenario selection in composite reliability assessment of deregulated power systems
(Journal article; Peer reviewed, 2014)Power market analysis should be incorporated in reliability assessments of deregulated power systems. For the Nordic power system, this is done by using The Multi-area Power-market Simulator (EMPS) for long-term power ... -
Simplified models of three-phase, five-limb transformer for studying GIC effects
(Journal article; Peer reviewed, 2018)The paper describes capabilities of a topological model of three-phase, five-limb transformer to accurately represent its response when subjected to geomagnetically induced currents. The model is validated by close agreement ... -
A two-level over-voltage control strategy in distribution networks with high PV penetration
(Peer reviewed; Journal article, 2021)Over-voltage in low voltage feeders due to the increasing penetration level of photovoltaic (PV) is a crucial issue to be addressed. There is a need to use more advanced voltage control methods to satisfy the response time ...
