Abstract

The incentive power market may lead to a high information cost if it is not informationally efficient. The paper analyzes the characteristic of the generation side power market mechanism model based on the designing economic mechanisms theory by the three GENCOs (Generation Companies) case. The result of analysis is that the mechanism model has four main features: the informationally efficient which means that the mechanism meets requirements of the observational efficiency, the communication efficiency and the low complexity of computing; the incentive compatibility which indicates that the resource allocation of the power market is Pareto Optimality and the social benefit achieves the maximization when GENCOs also achieve profit maximization; the decentralized decision which refers to preserving the privacy information of GENCOs; encouragement of competition which suggests that the mechanism encourages GENCOs to compete with each other healthily. DOI: http://dx.doi.org/10.11591/telkomnika.v11i4.2370

Abstract

Distributed Generation (DG) generates electricity from many small distributed energy sources or even customer’s small power plants. It always comes up with the terminal customer power quality management and the technology of energy cascade utilization. DG has lots of characteristics such as one single point of access, being power and being load, two operating mode in a grid or as an island, a great deal of application of power electronic devices, easily influenced by natural environmental factors etc. DG has impacts to the original grid in terms of the grid structure, the direction of power flow, the fault current level when a fault happens, etc and subsequently the relay protection mechanism must be looked into. This paper analyses the impact of accessing the DG on the distributed grid in three cases which are the DG accessing to the end of the distributed feeders, to the middle, and the DG accessing to lines, on relay protections. At the end of the paper it also comes up with improvements in detail. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2674
