Bilateral electricity transactions (BET) contribute much to stabilize electricity market operation, while the occurrence of bilateral transactions also presents new challenges to the market operation, transmission pricing, losses allocation, congestion management, etc. Corresponding modeling and analysis methodology to bilateral transactions are in great request. This paper proposes an approach on...
In deregulated market, available transfer capability (ATC) is a market signal refers to the capability of a system to transport above already subscribed transmission uses. It can provide significant information for power market participants. This paper deals with the evaluation of ATC for the integration of HVDC link with an AC power system. The computational model of ATC for AC-DC transmission system...
Based on actual characteristic of Chinese power system, starting from the practice, this paper puts forward auxiliary service compensation mechanism designing principles in present Chinese power market. Following the spirit and the idea of provisional measures of auxiliary services management of the grid-connected power plant, combining the actual situation of wind power in China, this paper studies...
The issue of power quality in the distribution system is always in sense of the concern. With the high penetration of distributed generation (DG) currently, it tends to be more complicated. This paper presents a new approach to evaluate impacts of the DG on power quality of the distribution network. In the process an objective function will be modeled, which will be solved by the optimization toolbox,...
Microgrid technologies are highly developed in low voltage networks, improving the power supply reliability and energy efficiency. Therefore, in this paper, the concept, including the configuration, principle and operation of microgrid, will be specified, comparing the microgrid with the prior distributed generation. Additionally, in order to justify the feasibility, the economical benefit analysis...
Available Transfer Capability (ATC) is an important index for determining power delivery contracts and managing transmission congestion. In power markets, large amount of uncertainties and dynamic, continuous and time-varying features of power systems have great impacts on ATC. In this paper a novel method is proposed to select the uncertainty faults affected ATC greatly, then the calculation time...
In electricity markets, the network is expected to transfer more power to promote profit, but the transfer capability will be affected by uncertainties. In order to quantify the probability and consequence of these uncertainties, the theory of risk is proposed to assess the available transfer capability (ATC). The means clustering method is used to layer the ATC values considering the uncertainties...
