Congestion management is deal with in this paper. The algorithm proposed is based on active and reactive power dispatches of critical nodes, determined from a detailed sensitivity analysis. The electricity market considered is a hybrid model, in which firm transmission rights may also be observed. The proposed algorithm is assessed and its capabilities evaluated for a typical test system. Manuscript profile

In competitive electricity market, maximizing the profit is the main objective in company’s decision making. Hence, Transmission companies (Trans Cos) are not interested in improving reliability and expanding existing structures without financial benefits. On the other hand, consumers demand more reliable and high quality power. In this paper, transmission insurance plan is proposed as an incentive method to improve the reliability of electrical power transmission. In this method, an insurance contract concluded between insurance company and every customer. Insurance company spend a part of its revenue to increases the reliability of the transmission system and also pays for compensation of consumers not supplied energies. The proposed method is studied in a network with six buses. Results show that the proposed method increases network reliability. Manuscript profile

Energy exchange among the electricity markets is a new issue in modern power systems. This issue, especially in Europe, has been identified as a market coupling. In this paper, a framework for congestion management and clearing of multiple electricity markets, in which the market participants can place their bids simultaneously in different markets across an interconnection, is proposed. In this framework, the markets dispatch the energy and the reserve, independently. A central coordinator entity, then, runs the allocation of transmission capacity among the electricity markets. Three methods for simultaneous clearing of the energy and reserve are also proposed. The possibility of implementation of the proposed methods in multiple markets is discussed. The numerical results for three-area 15-bus and IEEE RTS-96 test systems in a triple-market case are presented, to demonstrate the effectiveness of the proposed approach as compared with the other approaches.

In recent years, there has been an increasing attention in energy exchange among the various countries or areas. One of the methods for energy exchange, with coordinated by the area operators, is participation of producers and consumers in other area markets directly. In this paper, for multi-area power systems that there is a single market in each area (multiple markets structure), a mechanism for power exchange management is proposed. In the mentioned structure, the participation of external bus players in each market is possible. In the designed mechanism, the power exchange management is done by a proposed central coordinator entity. The coordinator performs the management of power exchange in an iterative decision-making process to maintain system security by using a technical approach. The simulation studies for a triple-market case in the standard three areas system (IEEERTS-96) are presented to validate the effectiveness of the proposed mechanism. Manuscript profile

With the advent of electricity markets and the creation of a competitive environment in power systems, proper allocation of transmission cost among network users (consumers and producers) is essential to help the investment of transmission network, effectively. In this paper, a hybrid method for transmission cost allocation based on the effect of transmission facilities in system reliability and their merchant value is proposed. In the proposed method, first, the users' benefit in the electricity market and in other words, the merchant benchmark in cost allocation has considered. Second, cost allocation considering the effect of facilities in system reliability which are consist of factors of system security and adequacy and the benefit of users with these factors is done. For the implementation of the proposed method, the capacity of all facilities includes lines and transformers are divided into four sections consist of merchant capacity, contingency capacity for maintaining security, future capacity for maintaining adequacy and invalid capacity. The numerical results in a 3-bus and the IEEE 30-bus test system are presented to demonstrate the effectiveness of the proposed method and compare to other methods. Manuscript profile

False data injection attack (FDIA) is a destructive cyber threat to the economic performance of electricity markets in smart grids. A cyber attacker can make a huge financial profit by implementing an FDIA through penetrating the virtual transactions of the electricity markets and manipulating electricity prices. In this paper, a new approach to planning an absolutely stealthily FDIA is presented with the aim of achieving maximum financial profit from the perspective of a cyber attacker participating in virtual transactions from two markets of day-ahead (DA) and real-time (RT). A common hypothesis in studies of FDIAs against electricity markets is that the attacker has complete information about the smart grid. But the fact is that the attacker has limited resources and can hardly access all the network information. This paper proposes a robust approach in designing an attack strategy under incomplete network information conditions. In particular, it is assumed that the attacker has uncertainties about the network modeling matrices. The validity of the proposed method is evaluated based on the IEEE 14-bus standard system using the Matpower tool. Numerical results confirm the relative success of the proposed attack in cases of varying degrees of incomplete information. Manuscript profile
