Approximate Analytical Solutions of Power Flow Equations Based on Multi-Dimensional Holomorphic Embedding Method
It is well known that closed-form analytical solutions for AC power flow equations do not exist in general. This paper proposes a multi-dimensional holomorphic embedding method (MDHEM) to obtain an explicit approximate analytical AC power-flow solution by finding a physical germ solution and arbitrarily embedding each power, each load or groups of loads with respective scales. Based on the MDHE...
متن کاملHydrothermal Optimal Power Flow Using Continuation Method
The problem of optimal economic operation of hydrothermal electric power systems is solved using powerful continuation method. While in conventional approach, fixed generation voltages are used to avoid convergence problems, in the proposed algorithm, they are treated as variables so that better solutions can be obtained. The algorithm is tested for a typical 5-bus and 17-bus New Zealand networ...
متن کاملFundamentals of the Holomorphic Embedding Load-Flow Method
The Holomorphic Embedding Load-Flow Method (HELM) was recently introduced as a novel technique to constructively solve the power-flow equations in power grids, based on advanced complex analysis. In this paper, the theoretical foundations of the method are established in detail. Starting from a fundamental projective invariance of the power-flow equations, it is shown how to devise holomorphici...
متن کاملNumerical Polynomial Homotopy Continuation Method to Locate All The Power Flow Solutions
The manuscript addresses the problem of finding all solutions of power flow equations or other similar nonlinear system of algebraic equations. This problem arises naturally in a number of power systems contexts, most importantly the direct methods for transient stability analysis and voltage stability assessment. Here we introduce a novel form of homotopy continuation method called the numeric...
متن کاملVoltage Stability Assessment via Continuation Power Flow Method
1 Abstract — This paper presents a potential algorithm for continuation power flow method in voltage stability assessment. Modified continuation power flow method termed as MCBF was developed which solved the solution of bifurcation point at the Q-V curve. The solvability of power flow at the bifurcation point beyond the maximum loadability point of a system was achieved through the implementat...
