Probabilistic Power Flow Calculation Considering the Correlation of Distributed Power Sources
2021 IEEE International Conference on Advances in Electrical Engineering and Computer Applications (AEECA), 2021Distributed new energy power generation is a supplement to the existing power generation model. At present, A large number of distributed new energy power sources are connected to the AC distribution network. In order to explore the influence of the correlation of distributed power output on the AC distribution network, this paper proposes a method for

A new probabilistic power flow analysis method
IEEE Transactions on Power Systems, 1990A method for the simulation of the composite power system is proposed for the purpose of evaluating the probability distribution function of circuit flows and bus voltage magnitudes. The method consists of two steps. First, given the probabilistic electric load model, the probability distribution function of the total generation of generation buses is ...

First-order probabilistic harmonic power flow
IEE Proceedings - Generation, Transmission and Distribution, 2001There is an increasing interest in standards and technical literature on the probabilistic characterisation of voltage and current harmonics in multiconvertor power systems. Characterisation requires the expression of input data of the harmonic penetration modelling by random variables and application of probabilistic techniques of analysis.

Probabilistic power flow using novel wind and solar probabilistic models
2016 IEEE Power and Energy Society General Meeting (PESGM), 2016Renewable based distributed generators are being used extensively owing to the benefits they offer for both utilities and investors. With the spread of these DGs in power systems, A precise model that follows the stochastic behavior of wind or solar is crucial for power system planning and operation.

Probabilistic Power Flow for Power Quality Assessment of Islanded Microgrid
2018 IEEE International Conference on Probabilistic Methods Applied to Power Systems (PMAPS), 2018This paper presents a new approach in the evaluation of power quality indices for microgrids operating in islanded mode. The indices are estimated considering uncertainties associated with: load forecast error, generator outages and the stochastic behavior of the power output of renewable energy sources.

A novel approach to account for uncertainty and correlations in probabilistic power flow
IEEE PES Innovative Smart Grid Technologies, Europe, 2014Power system security assessment techniques can greatly benefit from the adoption of probabilistic approaches, as these can thoroughly describe the effect of uncertainties on the operating condition. The paper proposes a methodology to evaluate the probability of exceeding operational constraints under normal and contingency situations, accounting for ...

A method for probabilistic harmonic load‐flow analysis in power systems
European Transactions on Electrical Power, 1998AbstractA new probabilistic method is presented for the harmonic load‐flow analysis in electrical power systems. In the method, the network is modelled using the bus impedance matrix at each harmonic order. The load flow is solved by a current injection method.
