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...
Considering the randomness of photovoltaic (PV) output and load, the paper proposes a new method to analyze PV power penetration limit based on probabilistically optimal power flow. The proposed model based on chance constrained programming, is a nonlinear programming model with multi-constraints which has random variables. It takes the maximal PV power capacity that can be accepted by power grid...
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...
Available Transfer Capability (ATC) is an operating index that plays an important role in guiding intra-area electricity trade for interconnected systems. Continuation power flow (CPF) is the main calculation approach used to determine ATC. But in the conventional CPF method, a specific proportional linear nodal power injection mode is widely adopted, accordingly, ATC achieved by this kind of the...
Available Transfer Capability (ATC) is a measure of the transfer capability remaining in the physical transmission network for further commercial activity over and above already committed uses. Putting forward against the defect that the traditional contingency selection method uses single index to enumerate states or disturbances, this paper introduces the active power behavior index and the voltage-reactive...
Available transfer capability (ATC) is defined as a measure of the system's capability for transfers of power for further commercial activity, over and above already committed uses. In practical power markets, ATC can provide important information for transmission customers, system operators and power marketers. The assessment of ATC should be carried out to assure the secure, economic, stable and...
In practical power markets, Available Transfer Capability (ATC) is crucial for transmission customers, system operators and power marketers to make a good choice. It is an indication of the expected transfer capability remaining on the transmission network. In order to assure the secure, economic, stable and reliable operation of power systems, the assessment of ATC should be carried out instantly...
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...
With the increasing expansion of AC/DC transmission system scale, the research on available transfer capability (ATC) for AC/DC transmission systems has important academic and practical significances to AC/DC transmission system planning, operation and reliability evaluation. However, most of the present researches on the ATC calculation are only suitable for AC transmission system, few is about the...
Expanding the extra high voltage AC/DC hybrid transmission system and improving the transfer capability of the network are the primary tasks of the power network in China. With the increasing expansion of AC/DC transmission system scale, the super large scale hybrid network has taken shape in china, then the systematic research on ATC calculation model and algorithm for AC/DC systems is urgently needed...
This paper presents an integrated framework for evaluating impacts of demand side management (DSM) on composite generation and transmission system reliability. A set of load management models for peak clipping/shifting and valley filling, strategic conservation and strategic load growth are presented. Composite DSM actions in the power system's diverse areas are also modeled. Composite system reliability...
It is very important and necessary to calculate total transfer capability (TTC) incorporating flexible alternate current transmission system (FACTS) devices in power markets and analyze impacts of FACTS on TTC. Calculating TTC incorporating with FACTS devices is an optimal problem constrained by some equalities and inequalities. This paper proposes a mathematical model for calculating TTC incorporating...
