Generation Expansion Planning with High Penetration of Wind Power

Abstract Worldwide thrust is being provided in generation of electricity from wind. Planning for the developmental needs of wind based power has to be consistent with the objective and basic framework of overall resource planning. The operational issues associated with the integration of wind power must be addressed at the planning stage. Lack of co-ordinated planning of wind turbine generators, conventional generating units and expansion of the transmission system may lead to curtailment of wind power due to transmission inadequacy or operational constraints. This paper presents a generation expansion planning model taking into account fuel transportation and power transmission constraints, while addressing the operational issues associated with the high penetration of wind power. For analyzing the operational issues, security constrained unit commitment algorithm is embedded in the integrated generation and transmission expansion planning model. The integrated generation and transmission expansion planning problem has been formulated as a mixed integer linear problem involving both binary and continuous variables in GAMS. The model has been applied to the expansion planning of a real system to illustrate the proposed approach.

Integrated Energy System

Integrated energy systems can provide a more efficient supply than individual systems by using resources such as cogeneration. To foster efficient management of these systems, the flexible operation of cogeneration resources should be considered for the generation expansion planning model to satisfy the varying demand of energy including heat and electricity, which are interdependent and present different seasonal characteristics. We propose an optimization model of the generation expansion planning for an integrated energy system considering the feasible operation region and efficiency of a combined heat and power (CHP) resource. The proposed model is formulated as a mixed integer linear programming problem to minimize the sum of the annualized cost of the integrated energy system. Then, we set linear constraints of energy resources and describe linearized constraints of a feasible operation region and a generation efficiency of the CHP resource for application to the problem. The effectiveness of the proposed optimization problem is verified through a case study comparing with results of a conventional optimization model that uses constant heat-to-power ratio and generation efficiency of the CHP resource. Furthermore, we evaluate planning schedules and total generation efficiency profiles of the CHP resource for the compared optimization models.

La Red

En la última década, un gran número de trabajos de investigación han abordado el problema de la expansión de los sistemas de potencia, coordinando en un solo problema de optimización el planeamiento de expansión de la generación (GEP, Generation Expansion Planning) y el planeamiento de expansión de la transmisión (TEP, Transmission Expansion Planning). El GEP normalmente se lleva a cabo sin tener en cuenta las restricciones de red y desde una perspectiva energética. Por otro lado, el TEP busca encontrar los refuerzos en la red, que atiendan una demanda futura de forma económica y confiable. La integración de estos problemas ha sido abordada utilizando diferentes métodos, modelos y funciones objetivo. En este artículo se presenta una revisión bibliográfica del problema del planeamiento integrado GEP-TEP desde diferentes puntos de vista como su modelado, métodos de solución, consideraciones de confiabilidad, entre otros. En la literatura especializada se encuentran artículos de revisión que caracterizan de forma independiente los problemas GEP y TEP. Sin embargo, no se encuentran revisiones que aborden problema GEP-TEP integrado. Surge entonces la necesidad de caracterizar los aspectos del planeamiento de la expansión integrada de los sistemas de potencia, con el propósito de proporcionar herramientas de consulta para los investigadores en este campo.
