This paper presents a model for reliability evaluation of Microgrids with Distributed Generation based on renewable energy resources. In this approach, DG participates in the network operation coordination as an active agent and not as a decentralized generation under which the utility has no control. Stochastic models are considered for representing generation availability related to wind ener...

Clean and sustainable renewable energy technology is going to take responsibility of energy supply in electrical power systems. Using renewable sources improve the environment and reduce dependence on oil and other fossil fuels. In distribution power system, utilizing of wind and solar DGs comprises some advantages; consist of loss and emission reduction, and also improvement of voltage profile...

Utilizing distributed generations (DGs) near load points has introduced the concept of microgrid. However, stochastic nature of wind and solar power generation as well as electricity load makes it necessary to utilize an energy management system (EMS) to manage hourly power of microgrid and optimally supply the demand. As a result, this paper utilizes demand response program (DRP) and battery t...

Current commercial software tools for transmission and generation investment planning have limited stochastic modeling capabilities. Because of this limitation, electric power utilities generally rely on scenario planning heuristics to identify potentially robust and cost e↵ective investment plans for a broad range of system, economic, and policy conditions. Several research studies have shown ...

the people’s republic of china is an ever rising world power and islamic republic of iran is one of the most powerful countries in the persian gulf region. the ever increasing world needs for oil and the role of iran and persian gulf in satisfying this need has made these relations more significant. the foreign policy of the fifth generation of leadership in people’s republic of china towards t...

The exponential growth of unpredictable renewable power production sources in the grid results difficult-to-regulate reactive power. ultimate goal optimal dispatch (ORPD) is to find voltage level all generators, transformer tap ratio, and MVAR injection shunt VAR compensators (SVC). More realistically, ORPD problem a nonlinear multi-objective optimization problem. Therefore, this paper, formula...

some geothermal reservoirs have temperatures below boiling point and therefore natural steam can not be produced for power generation. refrigerant power cycles may be then employed to recover low temperature heat. in this article study is made of the power cycles of six different relligrants and most suitable refrigerants for this purpose are suggested

In this paper a novel stochastic fundamental European electricity market model (E2M2s) is applied to estimate the value of electricity produced by wind turbines. The principle of E2M2s is cost minimisation in the European power network. The model determines the marginal system costs mainly as a function of available generation and transmission capacities, primary energy prices, plant characteri...
