SEQUENTIAL OBJECTIVE LINEAR-PROGRAMMING FOR GENERATION PLANNING

Generation planning usually involves finding a generation expansion and operating policy that minimizes present worth cost while meeting projected demands and other imposed constraints. However, the planning process is becoming increasingly complex with a number of objectives becoming increasingly desirable. In addition to minimum revenue requirements, other possible objectives include minimization of new power plant construction, maximization of reliability, minimization of public health hazard (e.g. via emitted pollutants), and minimization of environmental hazards (e.g. via heat rejected to bodies of water). These objectives have been evaluated using a sequential objective linear programming model for generation planning. Results show that substantially different planning decisions must be made depending on the objective for optimization, even though the different policies result in roughly comparable consumer costs. © 1979 IEEE
