The study on the energy-conservation power generation dispatch
2009 International Conference on Sustainable Power Generation and Supply, 2009At 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), 2012The 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, 2015Transmission 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

Impacts of Wind Power on Thermal Generation Unit Commitment and Dispatch
IEEE Transactions on Energy Conversion, 2007This 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.

Dispatchable solar photovoltaic power generation planning for distribution systems
2017 IEEE International Conference on Industrial and Information Systems (ICIIS), 2017The paper presents two multi-year optimization frameworks for solar photovoltaic power generation planning and management to make it dispatchable while maximizing the net present value of the investment: 1) simultaneous optimal planning of battery energy storage with solar photovoltaics, 2) aggregated capacity planning of solar photovoltaic with ...

The Minimum MVAR Generation as an Effective Criterion for the Reactive Power Dispatching
IFAC Proceedings Volumes, 1980Abstract The aim of the reactive power optimization is to improve as much as possible the quality of the service. The main efficiency figures taken into account are the minimum losses in the transmissio system, the warranty of a determined voltage level for the consumers and the maximum reactive margin in the generating units.

Distributed, anytime optimization in power-generator networks for economic dispatch
2014 American Control Conference, 2014This paper considers the economic dispatch problem for a group of power generating units communicating over an arbitrary strongly connected, weight-balanced digraph. The goal of the group is to collectively meet a specified load while respecting individual generation bounds and minimizing the total generation cost, which corresponds to the sum of ...

Economic Dispatch for Power Generation System Incorporating Wind and Photovoltaic Power
Applied Mechanics and Materials, 2013With the higher penetrations of wind and photovoltaic power in system, the randomness of its outputs adds amounts of uncertainty to system generation planning and scheduling. This paper formulates a day-ahead power economic dispatch model based on the uncertainty information of wind and photovoltaic power prediction obtained by prediction interval of ...

Dispatchable wind power generation planning for distribution systems
2017 7th International Conference on Power Systems (ICPS), 2017In this paper, a set of new planning strategies are proposed to optimally accommodate aggregated capacity of wind farms with special switching arrangements to make these dis-patchable. The goal is to mitigate the issues of intense renewable power penetration on distribution systems such as wind power curtailment, reverse power flow problem, high ...
