A microgrid can be operated in on-grid or off-grid, mode using distributed energy resources (DER), among which combined heat power can play an important role in increasing the total energy efficiency. This paper reports the total solutions to the problem of scheduling DER including CHP and their dispatch, called a generation application package. To increase the accuracy of forecasting, this pap...
Introduction: Optimal power flow (OPF) is an enhanced form of the economic dispatch (ED) optimisation problem where both active and reactive powers are treated as control variables and adjusted to minimise generation cost while observing associated power flow constraints. The constraints include but are not limited to thresholds on bus voltages, reactive power generation and the thermal ratings...
Power system generation scheduling is an important issue both from the economical and environmental safety viewpoints. The scheduling involves decisions with regards to the units start up and shut down times and to the assignment of the load demands to the committed generating units for minimizing the system operation costs and the emission of atmospheric pollutants. As many other real-world en...

abstract background: attention to different aspects of self‑efficacy leads to actual evaluation of self‑efficacy about physical activity. this study was carried out in order to design and determine psychometric characteristics of a questionnaire for evaluation of self‑efficacy about leisure time physical activity (selpa) among iranian adolescent boys, with an emphasis on regulatory self‑efficac...
In this work, we study the problem of determining the minimum scheduling length that can satisfy end-to-end (ETE) traffic demand in scheduling-based multihop WSNs with cooperative multiple-input multiple-output (MIMO) transmission scheme. Specifically, we present a cross-layer formulation for the joint routing, scheduling and stream control problem by incorporating various power and rate adapta...
This paper presents the status of real time grid operation in India with regulatory mechanism in place. Open access to transmission is encouraging short term and long term bilateral / multi-lateral contract in power market creating de facto a platform for power exchange to operate with various participants – buyers, sellers and traders in position. Index Terms — open access, power market, power...
Hydro-power plants are able to produce electrical energy in a sustainable way. A known format for producing is through generation scheduling, which task usually established as Unit Commitment problem. The challenge this process define the amount of that each turbine-generator needs deliver plant, fulfill requested dispatch commitment, while coping with operational restrictions. An optimal sched...
A campus based smart micro grid model that combined power and heat is presented. In this study, optimal scheduling of distributed generations inside these smart micro grids is determined based on demand forecasting, solar power forecasting and wind power forecasting by artificial neural network (ANN). The proposed model is then evaluated through economical efficiency, environment efficiency and...
