Energy price risk management
The price of electricity is far more volatile than that of other commodities normally noted for extreme volatility. Demand and supply are balanced on a knife-edge because electric power cannot be economically stored, end user demand is largely weather dependent, and the reliability of the grid is paramount. The possibility of extreme price movements increases the risk of trading in electricity ...
متن کاملOptimal energy management of the photovoltaic based distribution networks considering price responsive loads, energy storage systems and convex power flows.
Nowadays, presence of photovoltaic systems in distribution network is not without challenge and it may not have economic productivity for the system under the lack of optimal management. Energy storage systems are able to cope with this problem. Therefore, in this paper, a new method is proposed for energy management of the distribution networks in order to show that how presence of the energy ...
متن کاملGrid-price-dependent Energy Management of a Building Supplied by a Multisource System Integrated with Hydrogen
This paper studies power management in a grid-tied hybrid energy system consisting of photovoltaic array, wind turbine, fuel cell, electrolyzer, hydrogen storage tank and a combinational heating system to supply the thermal and electrical demand of a building. Moreover, the hybrid system is capable of exchanging power with local grid. Thus, variable daily buying and selling tariffs are also tak...
متن کاملRisk Management: Evidence from Oil Price Hedging in Highway Procurement
There is little empirical evidence about risk management heterogeneity across firm types. I evaluate a policy that shifts oil price risk in highway procurement from the private sector to the government, reducing the cost of hedging to zero. In a tripledifferences design using data from Kansas and Iowa, I show that firms value hedging oil price risk between the auction and commencement of work. ...
متن کاملPrice Discovery & Risk Management in an Industrialized Pork Sector
The process of industrialization in the swine industry has been written about extensively in recent years by Grimes, Barkema and Cook, Hurt, Rhodes, Boehlje and Schrader and others. The purpose of this paper is to concentrate on the pricing issues that have arisen during this process of industrialization. These issues include the diminishing role of open competitive markets and the increasing r...
