After restructuring in power systems, Independent System Operators (ISO's) are looked for an appropriate auction mechanism to find the market operation point. In deregulated electricity markets, Offer Cost Minimization (OCM) auction is used to minimize the total bid cost for selecting offer and demand bids. But a uniform market clearing price (MCP) or Locational Marginal Price (LMP) is used for consumer payments. Hence, the minimized bid cost is different from settlement cost. The used mechanisms are for manufactures offer and their cost functions optimization. The Payment Cost Minimization (PCM) is one of the mechanims that affect directly on the consumers payment and lead to reduction of... 

Electricity has been known as one of the humans’ essential needs. The emergence of a competitive environment in most aspects of humans life and its considerable impact on the economic system in recent years has promoted this idea that the electricity should be traded as a commodity. In this business, the competition has been based on the convenient access for subscribers, and the exclusive electricity environment has became a competitive environment. Therefore, new roles have emerged. These roles take place in the direction of generation, transmission and distribution of electrical energy with the aim of improving them. Retailer is one of the emerged roles for restructuring in the field of... 

Smart grids enable the implementation of novel energy management schemes for network operators. The restructuring of the power grid and the smartening of consumers, in addition to addressing environmental issues faced by traditional networks, have enabled many capabilities in the power grid, such as increasing network flexibility, peak shaving, and slowing down equipment obsolescence. The use of novel schemes, however, comes with its own set of challenges. One of these challenges is the uncertainty in the network, particularly on the supply and demand sides. Another challenge is the level of consumer engagement in energy management schemes. In this research, which is based on energy sharing,...
