Interval power flow analysis of microgrids with uncertainties: an approach using the second-order Taylor series expansion

A Study of Prediction Accuracy of English Test Performance Using Data Mining and Analysis

“…To simplify it, this paper incorporates Taylor's series. The definition of Taylor's series is as follows [23].…”

An interval power flow for unbalanced distribution systems based on the Three-Phase Current Injection Method

“…Note that the droop constant 𝐾 𝑓 is often referred to as the inverse of the generation unit statism and is generally less than 5% in the system base according to [32][33][34]. This constant may be associated mainly for rotating electrical machines and for Voltage Source Inverters (VSI) used for the connection of DG units into to distribution networks.…”

“…This constant may be associated mainly for rotating electrical machines and for Voltage Source Inverters (VSI) used for the connection of DG units into to distribution networks. The frequency variations are more expressive within microgrids environment due to the possibility of islanded operation [34]. However, it can be easily incorporated to the set of equations associated with the current injection method as described in [32] in order to calculate the system frequency.…”

“…New simulations are conducted in order to demonstrate the efficiency of the proposed method in this situation being the 69-bus test system used for the computational simulations of the case study described in Section 3.4. with the introduction of DG (Distributed Generation) units. The 𝐾 𝑓 droop constants of the generation units are set equal to 50 kW/Hz as adopted in [34] for the 69-bus test system.…”

“…It can be noted that similar results are obtained when compared to the traditional MC simulations, proving the efficiency and viability of the proposed method. The frequency variations are not expressive due to the connection of the substation (main energy source) to the distribution network as discussed in [34].…”
