Among the different options available for market clearing mechanisms, offer cost minimisation mechanism is being used in most electric power markets. The payments are then calculated based on locational marginal prices (LMPs). The payments can be significantly higher due to the inconsistency of the clearing and pricing mechanisms. Payment cost minimisation (PCM) mechanism which directly minimises the total payment has been recently proposed to solve this issue. In this study, an auction mechanism is proposed for payment to suppliers minimisation (PSM) based on the LMPs instead of consumers payment minimisation (CPM). Using a proper formulation for the supply side reserve LMPs, the complete... 

There are different choices for auction and settlement mechanisms in electricity markets; however, selecting the appropriate mechanisms is too hard. Traditionally, the offer cost minimization (OCM) mechanism that minimizes the total offer cost is used as the clearing mechanism, and payments are calculated based on locational marginal prices (LMPs). Under this setup, the clearing and settlement mechanisms are inconsistent, since the minimized cost is different from the total payment cost. Some recent studies have proposed the payment cost minimization (PCM) mechanism. However, the discussion is still open, and different aspects of these mechanisms are yet needed to be analyzed. This paper... 

One of the most used types of auctions in the smart grid is the double auction, in which both buyers and sellers can respectively submit their bids and asks to participate in the auction. In recent years, many schemes have been designed to propose a double auction mechanism for the smart grids; however, few of these schemes consider the information security aspects and users’ privacy. In this paper, we propose a protocol that helps different double auction mechanisms be implemented securely in the smart grids. This protocol not only can satisfy the security requirements of a double auction scheme but is also compatible with the smart grid technologies. In this scheme, in order to preserve...
