Este trabalho trata sobre a sintonização robusta de Estabilizadores de Sistemas de Potência (ESP) na presença de sinais remotos em um sistema de potência multimáquinas. Os sinais remotos são utilizados para amortecer modos de oscilação do tipo interárea e o tempo de latência é modelado através da aproximação de Padé. A função objetivo considerada para sintonia dos parâmetros dos ESPs almeja maximizar o amortecimento do sistema elétrico de potência para todos os modos de oscilação eletromecânicos e minimizar o impacto das incertezas no tempo de latência, intríseco aos sinais remotos, empregando a técnica da matriz de soma bialternada. A metodologia proposta foi aplicada a um sistema teste composto por 7 barras e 5 geradores considerando vários pontos de operação. A metodologia apresentada garantiu um amortecimento mínimo para todos os pontos de operação e assegurou a estabilidade absoluta do sistema teste para situações onde o tempo de latência é considerado um parâmetro incerto.

“…This has been addressed by the development of robust optimisation methods, which conduct operational optimisation within an established range of WP output rather than based on a WP output prediction curve with associated error obtained beforehand [8]. The application of robust optimisation in microgrids mainly consists of two components, including robust control [9], which explicitly considers renewable energy power output uncertainty, and robust dispatch, which seeks to obtain the lowest cost generation dispatch that satisfies various constraints such as system power balance, generator power output, and ramping limits [9]. Taguchi's orthogonal array (OA) method for an energy management system (EMS) was proposed to address the uncertainties associated with the real‐time market price by formulating a min‐max robust optimisation problem [10].…”

Combined cooling, heating, and power (CCHP) microgrids are a special form of a microgrid that is attracting increasing attention. This study contributes to the goal of minimising the operation cost of CCHP microgrids by proposing a hierarchical two‐stage robust optimisation dispatch model for multiple CCHP microgrid systems. The uncertainties associated with wind power output, electric power, heating, and cooling loads, and transmission line failures are considered in the proposed model. Moreover, the electricity purchasing and selling prices of each microgrid are independently determined. The proposed model applies the outputs of fuel cells, energy storage devices, and gas turbines, the distribution factor of waste heat, and the power transmission between the microgrids and an external grid as control variables. The optimised dispatch problem is solved using McCormick envelopes relaxation and a novel column and constraint generation algorithm that provides enhanced optimisation performance by implementing co‐evolutionary theory. In this way, the microgrid system is divided into several sections, and each section is represented as an individual min–max–min problem. The rationality and validity of the proposed model and the superiority of the solution performance of the improved algorithm are verified through simulation case studies involving a system composed of four CCHP microgrids.

“…Some researches obtained better PSS parameters via algorithm improvement [15], while some others converted the parameter solution issue into the multiobjective optimization problem [16]. For the multimachine systems, more consideration is given to the robustness improvement [17][18][19], while the effectiveness of PSS parameters is not considered comprehensively at the meantime.…”

In this paper, we proposed the comprehensive damping effect method to optimize the PSS parameters. Different from other studies, the optimization in this paper is based on both the amplitude-frequency and the phase-frequency properties, while other studies mainly focus on the phase-frequency characteristics. The actual grid data in Northern China are employed to verify the optimization effect in the multimachine system. The proposed method is compared with the engineering method, the existing optimization method, and the commercial software. The comparison shows that the PSS parameters obtained by the proposed method in this paper are superior to those obtained by the engineering experience, the phase-frequency optimization method, and the commercial software. In the cases of different phase-frequency range requirements, the wider the phase-frequency range is, the better the damping effect of the obtained parameters will be.
