It is very important to forecast electricity price in a deregulated electricity market for choosing the bidding strategy, and it is the most important signal for other players. It engulfs information for both customers and producers in order to maximize their profit. Thus, choosing the best method of price forecasting is a crucial task to have the most accurate forecast. In this paper the price...

In a deregulated market, the operator of a hydro storage power plant has to consider different market products as well as uncertainties in its prices for optimal scheduling. A suitable mathematical framework for such problems is stochastic dynamic programming. The critical aspect there is modeling, since efficient solution techniques are well known. We present a modeling approach, where the act...

The trade in commodity derivatives is widespread and trading volumes often surpass that of the underlying commodities. Commodity derivatives markets have seen a 60fold increase in the value of trade between 1998 and 2008. In 2008 the outstanding value of commodity derivatives equaled $13 trillion. This is twice the worldwide output of commodities, and about 21% of world GDP. Ideally derivatives...

Voltage stability is an important issue in the planning and operation of deregulated power systems. The voltage stability problems is a most challenging one for the system operators in deregulated power systems because of the intense use of transmission line capabilities and poor regulation in market environment. This article addresses the congestion management problem avoiding offline transmis...
