This paper develops a discrete operation optimization model for combined heat and powers (CHPs) in deregulated energy markets to maximize owners’ profits, where energy price forecasting is included. First, a single input and multi-output (SIMO) model for typical CHPs is established, considering the varying ratio between heat and electricity outputs at different loading levels. Then, the energy ...

In this paper, the problem of two-machine flow shop scheduling to minimize total energy costs under time-of-use tariffs is investigated. As the objective function of this study is not a regular measure, allowing intentional idle-time can be advantageous. So this study considers two approaches, one for non-delay version of the problem and the other one for a situation when inserting intentional ...

The introduction of Electric Vehicles (EVs) in the existing Energy Grid raises many issues regarding Grid stability and charging behavior. Uncontrolled charging on the customer’s side may increase the already high peaks in the energy demand that lead to respective increase in the energy prices. We propose a novel smart charging algorithm that maximizes individual welfare and reduces the individ...

as one of the most important products of iran, pistachio has a significant share in non-oil revenues. its annual foreign exchange earnings are over 800 million dollars. however, production of this nut in the country’s major production centers is faced with many problems regarding the efficiency and productivity of the inputs. this study was performed by using two-stage cluster sampling method. ...

The Power Trading Agent Competition (Power TAC) is a feature-rich simulation that simulates an energy market in a smart grid, where software brokers can buy energy in wholesale markets and sell energy in tariff markets to consumers. Successful brokers can maximize their profits by buying energy at low prices in the wholesale market and selling them at high prices to the consumers. However, this...

I study the general equilibrium implications of large-scale policies to improve energy efficiency, which are being implemented around the world to mitigate climate change. Energy efficiency policies “rebound” when economic responses undercut their direct energy savings. I develop an analytic general equilibrium framework that allows improvements in energy efficiency to affect output prices and ...

The implementation of economic projects by targeting the subsidies can have a great effect on the cost competitiveness of the industries and their products. The global steel industry has been considered as a basic key industry in the industrialized countries. It is also among the industries that may be seriously affected by the enforcement of subsidies. This industry, requiring energy and high-...
