This paper proposes a new analytical method for transmission power loss allocation for pool-based markets in restructured power systems. It is based on circuit laws and the concept of orthogonal projection. In this method, the current flow in each branch is divided into two components by using the superposition principle. The first one is due to the power transfer from generators to distributio...

Electricity markets in both developed and developing countries have been considerably reorganized over the previous two decades. The unbundling of generation transmission results restructured electricity market which enhances competition among traders regime open access. Therefore, pricing methods should be skilled translating costs into tariffs to allow participation, leads profitable effectiv...

By increasing the extraction of natural gas, its role in the restructured power systems is being expanded, due to its lower pollution. Iran has the second largest reserves of natural gas in the world and exports it to different countries. This paper represents long run analysis of natural gas export from Iran to Turkey as a case study, considering direct transfer and exporting via the power mar...

This paper is concerned with the protection of wind energy systems against the direct effects of lightning. As wind power generation undergoes rapid growth, lightning damages involving wind turbines have come to be regarded as a serious problem. Nevertheless, very few studies exist yet in Portugal regarding lightning protection of wind energy systems using numerical codes. A new case study is p...

This paper presents payoff allocation for PSS control service in the restructured power systems. The method is based on cooperative game theory by using the Shapley value concept. Because of the complexity and difficulty associated with the system dynamic performance of the PSS to a financial cost, ITAE performance index is used to evaluate the contribution of the PSS for increasing system stab...

Modern electric power systems are becoming over-stressed due to shrinking reserve margins, elevating electricity cost, permitting difficulties, and financial risks of bulk expansion. Demand-side integration (DSI) addresses these problems through programs that encourage the efficient and effective use of electricity in support of power systems and customer needs. A growing international communit...

Modern restructured power systems sometimes operate with heavily loaded lines resulting in power system to work under condition of higher power loss and higher voltage deviation, which may result in insecure operation of power system; even sometimes it may lead to voltage instability or system collapse. It is mainly due to continuous and uncertain growth and demand of electrical power. This pap...
