Abstract

This paper proposes a method calculating total transfer capability(TTC) and critical voltage using static power model based on real-time recording data, traditional power system dispatching calculation doesn’t consider load model, which does not agree with the real, this paper compares TTC and critical voltage under different load model and P-V curves, on which load model has a strong influence, so load modeling is necessary based on real-time data and is significant for improving system stability. The simulations show necessity and suitability of the method. DOI: http://dx.doi.org/10.11591/telkomnika.v11i4.2330

Abstract

This paper introduces a conventional synthesis power load model considering distribution network in PSASP, through analyzing the model structure and achieving process, proposes a power load model parameter identification method based on improved perturbed method. The paper gives parameters identification method of complete synthesis load model, including reactive power compensator parameters. The parameters identification method combines parameter identification process with sensitivity analyzing process together, not only can get model parameters but also can obtain the sensitivity of all parameters, which saves computing time and reduces the amount of calculation, the final simulation results prove the method is effective and feasible. DOI : http://dx.doi.org/10.11591/telkomnika.v12i5.5113
