Optimal Control of Micro-grid (MG) to Improve Voltage Profile Including Combined Heat and Power System
Journal Title: روش های هوشمند در صنعت برق - Year 2018, Vol 9, Issue 36
Abstract
Usually, in the studies of optimal control for the micro-grid with combined heat and power (CHP), economic and environmental goals have been raised. In these studies, the optimization of control devices and compensators that are aimed at improving the technical aspects of micro-grid has not been considered. Therefore, in this paper, these goals are considered simultaneously. In this paper the shunt capacitor, shunt reactor, static var compensator, load ratio control transformer, step voltage regulator and power generation of DGs are investigated as control variables with the aim of considering costs, losses and voltage profile improvement. The case under study is a distribution test system including 22 buses, which consists of photovoltaic and fuel cell. All network data is extracted from a real system. As a result, the system can completely represent a real system. In order to complete the study of the system, the emissions of fuel cells are considered in the objective function. The efficiency and output electrical and thermal power of the fuel cell are considered related to part load ratio as a real standard model introduced in previous studies.
