“…The amount of power flow on a transmission line between Node i and Node j is defined in Equation (3). All generator's offered quantity is given by its limits in Equation (4). Finally, the line flow limit can be modeled in Equation (5).…”

“…Monitoring line congestion is one of the important steps in power system operations. However, from the market perspective, any line congestion may cause LMP differentiation within the market area [4,23]. If there is no congestion, the result of the nodal market model is the same as the uniform market model.…”

“…Theoretically, if there is no transmission congestion in the system, there is no difference among zonal marginal prices. However, if transfer limits are active, then zonal marginal prices begin to split [4]. Another pricing method is nodal marginal pricing or, in other words, local marginal pricing where each location on the transmission grid, called a node, is expected to have a location-based marginal price.…”

In the electricity market, different pricing models can be applied to increase market competitiveness. Different electricity systems use different market structures. Uniform marginal pricing, zonal marginal pricing, and nodal marginal pricing methods are commonly used market structures. For markets wishing to move from a uniform pricing structure to a more competitive zonal pricing structure, the determination of price zones is critical for achieving a competitive market that generates accurate price signals. Three different pricing zone detection algorithms are analyzed in this paper including the k-means clustering and queen/rook spatially constraint clustering. Finally, the results of a case study for the Turkish electricity system are shared to compare each method.

“…Para analizar el estado del SEP después de que ocurrió una falla, se pueden utilizar diferentes metodologías como: flujo de potencia AC o DC; además existen técnicas como: flujos óptimos de potencia AC o DC; cada uno de estos métodos va a depender de la complejidad del problema que se desea resolver; por ejemplo, si se habla de flujo optimo DC se relaja al sistema linealizando las ecuaciones [7][8][9][10][11].…”

Revisión para la restauración optima de la operación del sistema eléctrico basado en criterios de calidad de energía y estabilidad

Las fallas que ocurren en el sistema de energía eléctrica tienen un gran impacto en la sociedad generando grandes pérdidas económicas y perdidas de energía eléctrica; por esta razón, es necesario tener un plan que permita restaurar el sistema eléctrico de una manera óptima y en el menor tiempo posible. Se realiza una revisión de las metodologías que permiten realizar una planificación de la restauración óptima de la SEP después de una falla debido a problemas que causan corte parcial de energía en ciertos puntos de la red. Con lo cual se puede implementar una heurística que permita elegir el camino óptimo para la restauración; es decir, proporcionará los pasos para ingresar los elementos que se ingresan, como son: las líneas de transmisión o centrales de generación, teniendo en cuenta la estabilidad del sistema y los índices de calidad que representan las restricciones del problema. Por lo tanto, los flujos óptimos de potencia se utilizan para conocer el estado del sistema posterior a la falla; de esta manera, los criterios de voltaje y potencia se utilizarán para ingresar a la heurística, además de utilizar programación lineal de entera mixta (MILP).

“…Like the UC problem, OTC is also formulated in the form of MILP. Although its theoretical background is studied and published by several groups [24][25][26][27][28][29][30][31], there is no reported use of OTC in business as of today. However, possible sub-applications of OTC in deregulated markets are discussed in Reference [32].…”

Regular transmission maintenance is important to keep the infrastructure resilient and reliable. Delays providing on-time maintenance increase the forced outage rate of those assets, causing unexpected changes in the operating conditions and even catastrophic consequences, such as local blackouts. The current process of maintenance schedule is based on the transmission owners’ choice, with the final decision of system operator about the reliability. The requests are examined on a first-come, first-served basis, which means a regular maintenance request may be rejected, delaying the tasks that should be performed. To incorporate optimization knowledge into the transmission maintenance schedule, this study focuses on the co-optimization of maintenance scheduling and the production cost minimization. The mathematical model co-optimizes generation unit commitment and line maintenance scheduling while maintaining N-1 reliability criterion. Three case studies focusing on reliability, renewable energy delivery, and service efficiency are conducted leading up to 4% production cost savings as compared to the business-as-usual approach.
