This paper presents a novel approach for estimating mode shape for participation (MSFP) among areas or main power plants involving inter-area oscillation (IAO) mode, by analyzing power deviation (ΔP) signals. The case study has been carried out on a planning case in East China Power Grid (ECPG). The results indicate that the proposed algorithm is effective, and imply its potential applicability in...
Excitation system plays a key role in realistic simulation and analysis of the dynamic performance of electrical power systems. However, simulation results with parameters provided by manufacture can usually not match the real operation. Therefore, parameter identification based on field data is focused on. In this paper, parameter identification methods based on particle swarm optimization (PSO)...
Excitation system plays a key role in realistic simulation and analysis of the dynamic performance of electrical power systems to a large extent. Therefore, it is desire to obtain the real parameter of the excitation system in order to study the dynamic performance of power systems. This paper presents a practical technique to address the excitation system identification. The measurement was performed...
This paper proposed a new algorithm to perform the online determination of the low frequency oscillation modes in large interconnected power system. First, the generator's active power and its speed deviation were represented in the form of generalized phasor and the relationship between their phase angles was deduced. Then a simple system was constructed to illustrate the correspondence between the...
Generation capacity investment holds the origin of the electric power supply chain, and creates significant impacts on the reliability of power supply service. Based on the system dynamics theory, this paper builds up a model that describes the development of electric power generation investment, and uses the model to perform the dynamic simulation of generation capacity investment in different market...
