Power Systems Restructuring

An overview on network cost allocation methods

“…The P R method, also known as postage stamp method, revised in [3] and [4], allocates costs proportionally to the power injected by each generator or by each demand. But, to do this, it's necessary to decide how much of the cost should be attributed to generators and demands.…”

“…The pro rata method, presented in [3] and [4], allocates costs to generators and demands according to the sum of active power produced/consumed by each generator/demand.…”

A Decentralized Approach for Optimal Wholesale Cross-Border Trade Planning Using Multiagent Technology

“…a) When , if the system has only one demand at node and it can be served by a single cheapest path from a source node with system constraints satisfied, i.e., available capacity along (2) It is clear that the corresponding tie line flow vector is also the global optimal solution of (1) for . This is because that there are no other demands in the system and there are no other paths that are cheaper than the selected path (otherwise the selected path wouldn't be the cheapest path, which conflicts with the known condition).…”

“…O VER the past decade, electric power systems have been undergoing deregulations to introduce competitions among market participants, see [1], [2]. Transmission open access for suppliers and customers is one of the most prevailing unbundling services [3], [4].…”

On the complexity of market power assessment in the electricity spot markets

“…In order to offer set of bids day-ahead for each hour 24 , , 1 k K = , the unit needs to decide when it would be scheduled according to some criteria. If the criteria do not account for SU and SD costs, this amounts to solving a decentralized ED [4]. If the UC constraints are accounted for, this amounts to solving a decentralized UC [1].…”
