In a deregulated power industry, estimation of power price and management of congestion is a major issues handled by market members. Modeling of sensible pricing structure of power systems is important to provide financial signals for electrical utilities. Locational Marginal Pricing technique is used to determine the energy price for transacted power and to manage the system congestion. In this paper...
This paper proposes an Optimal Power Flow (OPF) based Market clearing procedure using the Bacterial Foraging Optimization Algorithm (BFOA). A comparison is made between the proposed method and the auction-based method. The IEEE 30 bus system is taken for case study. It is found that the OPF method is more reliable for setting the price of electricity in a pool based electricity market compared to...
Equivalent Bilateral Exchange method of transmission pricing works for pool structure of power markets. The nodal charges for pool customers are calculated by creating virtual exchanges applying proportionate sharing principle. This paper provides a proposal for modifying the existing method in order to accommodate the bilateral transactions. The charges for existing pool customers are developed in...
The network model bases upon the energy hub concept, which was developed by the Vision of Future Energy Networks” (VoFEN) research group at ETH Zurich in the last years. Keynote of the concept is a combined optimization of different energy carrier. Synergetic effects are expected to give unusual optimization results, when allowing any possible energy conversion inside a specific area that constitute...
DC Optimal Power Flow (DCOPF) model calculates locational marginal prices (LMPs) in order to optimize the total operation cost of system. Generally, no account is taken for the cost of network topology uncertainty. In this paper, first, a DCOPF algorithm is presented to consider network topology uncertainty. The optimization function algorithm has three items that depend on the line and unit parameters...
This paper presents one of the OPF methodologies that allow performing scheduling and market auctioning simultaneously. The problem uses a non-linear model of electrical network, which allows taking into account voltage constraints, injections of reactive power and line current constraints. Consideration is also given to integral generation output constraints, ramp rate, and reserve constraints. Transformer...
