Impacts of Wind Power on Thermal Generation Unit Commitment and Dispatch

IEEE Transactions on Energy Conversion, 2007
This paper proposes a new simulation method that can fully assess the impacts of large-scale wind power on system operations from cost, reliability, and environmental perspectives. The method uses a time series of observed and predicted 15-min average wind speeds at foreseen onshore- and offshore-wind farm locations.

Dispatch modeling of a regional power generation system – Integrating wind power

Renewable Energy, 2009
Abstract A modeling tool has been developed which can be used to analyze interaction between intermittent wind power generation and thermal power plant generation in a regional electricity grid system. The model uses a mixed integer programming (MIP) approach to determine the power plant dispatch strategy which yields the lowest systems costs. In the

Multi-Area Power Generation Dispatch in Competitive Markets

IEEE Transactions on Power Systems, 2008
In competitive electric energy markets, the power generation dispatch optimization is one of the most important missions among generation companies-how to respond to the markets, dispatch their units, and maximize profits. This paper proposes an approach to incorporate power contracts, which include call and put options, forward contracts, and ...

Power dispatch and load control with generation uncertainty

2015 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2015
In this paper, we focus on the problem of joint load scheduling and generation management to better match supply and demand. We formulate an optimization problem to jointly minimize the generation cost and discomfort cost of the users subject to the voltage and power balance equations for the equivalent circuit of the power system.

Distributed dynamic economic dispatch of power generators with storage

2015 54th IEEE Conference on Decision and Control (CDC), 2015
This paper considers the dynamic economic dispatch problem for a group of generators with storage that communicate over a weight-balanced strongly connected digraph. The objective of the generators is to collectively meet a certain load profile, specified over a finite time horizon, while minimizing the aggregate cost. At each time slot, each generator

The study on the energy-conservation power generation dispatch

2009 International Conference on Sustainable Power Generation and Supply, 2009
At the present time, the country has carried out the measure of energy-saving power scheduling. The main object of this measure is to increase the efficiency and to reduce pollution which is important to the power stations. This paper calculated three kinds of equivalent price coefficient of energy and environment in the case of the lowest bidding ...

Economic dispatch of renewable power generators in a microgrid

2012 IEEE International Symposium on Alternative Energies and Energy Quality (SIFAE), 2012
The improvement of new energy generation technologies has supported the usage of renewable alternative sources in a distributed way based on an information structure known as a Smart Grid. In this work, we explore the applicability of the distributed generation concept in a small city with renewable energy provided by biomass and small hydro plants in ...

Optimization of generator Reactive Power Dispatch in restructured power systems

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
Transmission open access has increased the need for reactive power and voltage support in power systems with electricity markets due to the higher requirement for system security and reliability. A Reactive Power Dispatch Optimization (RPDO) method that can be used by the system operator to centralize the scheduling of reactive power from generators is
