The objective of this study is to propose a dynamic generator maintenance scheduling (GMS) algorithm for long-term power sector forecasting and planning studies in which electricity price and the resulting supply composition are determined with merit-order dispatch. Compatible with the GMS algorithm, a reasonable strategy for the utilisation of storage hydropower plants along with clear definitions for each stage including must-run renewable electricity generation modelling, calculation of reserve capacity, derivation of scenarios for storage hydropower plants and problem formulation is presented. Generation from storage hydropower plants are modelled such as must-run and price-dependent parts, to better approximate reality. The proposed structure is tested with real data of the Turkish system, with a demand and capacity projection in the long term. The results are compared with the actual maintenance plan of the base year and the general profile is evaluated as satisfactory. The results show that the GMS plan and profile may significantly change based on hydro and renewable generation expectation, future capacity evolution, and storage hydropower plant utilisation. Therefore, the proposed GMS algorithm can be utilised especially in long-term price forecasting and supply modelling studies, instead of using a fixed factor to represent the maintenance effect on available generation capacity.

Finding optimal schedules in a home energy management system Merdanoglu, Hakan; Yakici, Ertan; Dogan, O. Tufan; Duran, Serhan; Karatas, Mumtaz (Elsevier BV, 2020-05-01) In this study, we model and solve the scheduling problem embedded in a home energy management system (HEMS), which enables users to overcome the major obstacles in implementing demand response programs. The problem aims to find the minimum energy cost while taking into account the time-varying prices, generation from renewable sources, usage demands for each appliance in household, battery storage capacity and grid constraints. Due to the uncertainties in supply, demand and electricity price, a stochastic o...
Promoting the Investment on IPPs for Optimal Grid Planning TOR, Osman Bulent; Güven, Ali Nezih; Shahidehpour, Mohammad (Institute of Electrical and Electronics Engineers (IEEE), 2010-08-01) This paper presents a transmission expansion planning (TEP) model which coordinates investment decisions in monopolistic transmission and decentralized generator sectors. The proposed planning approach gauges transmission congestion and security constraints with respect to transmission investments while promoting investments on independent power produces (IPPs) through incentive payments. The paper includes discussions on incentive mechanisms and prioritization among qualified IPPs for several planning scen...
Integrated analysis of pressure response using pressure-rate convolution and deconvolution techniques for varied flow rate production in fractured formations Al-Rbeawi, Salam (Elsevier BV, 2018-03-01) This paper introduces an integrated analysis for pressure transient behavior of conventional and unconventional multi-porous media reservoirs considering varied flow rate conditions. It focuses on the applications of pressure-rate convolution and deconvolution techniques for analyzing pressure records of homogenous single porous media, double porous media, and triple porous media reservoirs. The tasks covered in this paper are: Deconvloving pressure response, characterizing and developing analytical models ...
Integrated deterministic approaches for productivity index of reservoirs depleted by horizontal wells and undergone multiphase flow conditions Al-Rbeawi, Salam (Elsevier BV, 2019-04-01) This paper introduces new integrated approaches for estimating pseudo-steady state productivity index (PI) and shape factor of oil and gas reservoirs drained by horizontal wells and dominated by multiphase flow conditions. These approaches couple PVT data, relative permeability curves, and pressure distribution models during pseudo-steady state flow (PSS). The objective is eliminating the uncertainties of applying single phase flow models and substantially comprising the realistic parameters that govern mul...
Predicted impact of collector and zeolite choice on the thermodynamic and economic performance of a solar-powered adsorption cooling system Baker, Derek Keıth (Informa UK Limited, 2007-04-01) Transient thermodynamic and capital cost models for an intermittent solar-powered adsorption cooling system are presented. The models are used to predict size and cost trends as the type of zeolite and collector, and maximum zeolite temperature (T-Z,T-Max), are varied. The best synthetic and natural zeolites considered have similar performance. The minimum cost system uses a flat plate collector for T-Z,T- Max < 160 degrees C and an evacuated tube collector for T-Z,T- Max > 160 degrees C. Collector costs do...
