Linear power-flow models in multiphase distribution networks
2017 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2017This paper considers multiphase unbalanced distribution systems and develops approximate AC power-flow models wherein voltages, line currents, and powers at the point of common coupling are linearly related to the nodal net power injections. The linearization approach is grounded on a fixed-point interpretation of the AC power-flow equations, and it is

Abstract This paper presents a new linear active power flow solution method. The new linear active power flow presents a better performance to calculate MW power flows, as opposed to MW flows, calculated in classical model with a DC power flow. The aforesaid proposed method is based on a decoupling principle. Therefore, the voltage angles and voltage

Linear Probabilistic Power Flow for Islanded Microgrids
2020 International Conference on Probabilistic Methods Applied to Power Systems (PMAPS), 2020The problem of power flow in islanded operation of microgrids is more complex than in interconnected mode due to the absence of a slack bus. In addition, the power flow must consider uncertainties in a probabilistic framework. Probabilistic power flow has a high computational cost due to the need to assess a large number of states and the use of ...

Linearized power flow for stochastic optimization
2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE), 2017The behavior of network constraints in economic dispatch and unit commitment problem is examined in this paper. It analyses the constraints related to the power flow in a stochastic programming tool and tests different approaches for transmission loss computation. This work is part of an ongoing effort to develop tools for stochastic analysis of hybrid

An AC power flow linearization for power system optimization using linear programming
2016 IEEE Electrical Power and Energy Conference (EPEC), 2016This paper presents a method for the linearization of the non-linear power flow equations, which can be used in mixed integer linear optimizations. The power flow equations are linearized around an operating point using the Taylor approximation.
