This work presents an optimization framework to aggregate the power and energy flexibilities in interconnected distribution systems. The aggregation is used compute day-ahead dispatch plans of multiple grids operating at different voltage levels. Specifically, proposed optimizes plan upstream medium (MV) grid accounting for flexibility offered by downstream low (LV) knowledge uncertainties stoc...

During extremely hot summer days, air conditioning systems are known as major electricity consumers in residential, commercial and industrial sectors. Moreover, high energy requirement of multiple-chiller plants may cause an interconnected power grid be faced with annual on-peak electrical demand, load-generation mismatch, voltage collapse and catastrophic wide area blackout. Therefore, this pa...

nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. in this paper, a new method i.e. water cycle algorithm (wca) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. wca is used to solve complicate...

As renewable energy penetration rates continue to increase in power systems worldwide, newchallenges arise for system operators in both regulated and deregulated electricity markets tosolve the security constrained unit commitment problem with intermittent generation (due torenewables) and uncertain load, in order to ensure system reliability and maintain cost effec-tiveness. In...

The application of power to gas (P2G) provides a new way to absorb intermittent renewable energy generation, which improves the efficiency of renewable energy utilization and provides the necessary flexibility for operating the integrated energy system. The electro-thermal integrated energy system with P2G is a new form of using energy efficiently. In this paper, we first introduce the technolo...
