Optimal Energy Dispatch and Maintenance of an Industrial Coal-Fired Combined Heat and Power Plant in Kazakhstan

“…The power system of Kazhakstan is presented in detail by a recent work (Assembayeva et al 2018;2019) A developing a spatial electricity market model for the power system of Kazakhstan and providing spatial electricity market data. A recent work (Zhakiyev et al, 2017) present a model for optimal energy dispatch and maintenance of an industrial coal fired combined heat and power plant in Kazakhstan. Moreover, Kerimray et al (2016) examine climate change mitigation scenarios and policies and measures in the case of Kazakhstan, while Kerimray et al (2018) investigate the energy transition to a coal free residential sector in Kazakhstan using a regionally disaggregated energy systems model.…”

Developing economies are in process of liberalizing their electricity markets, following similar process in developed economics. This process aims at establishing liquid energy exchanges that provide clear price signals, providing indications on the profitability of different operations: Production, retail, trading in interconnections. This paper aims at developing a unit commitment model for examining zonal market pricing in Kazakhstan. The latter has an extensive landscape but sparsely populated, while is also characterized by the high availability of domestic fossil fuels, but located in different sub-regions of the country. The provision of zonal price signals in such a power system in invaluable, as it enables the provision of clear price signals on the needed infrastructure and the estimation of the zonal hourly energy and technology mix. Moreover, in enables the formation of dynamic bidding strategies by market participants in cases with favourable conditions, such as the implementation of scarcity pricing. This paper presents a unit commitment model that used to assess different bidding strategies and to provide zonal price signals. The strategies are formed, depending on the technology type and fuel prices comparison. Results provide clear signals on needed infrastructure among zones in Kazakhstan. It also shows that dynamic biding can lead to market coupling. Finally, it indicates the importance of institutional capability to monitor bidding strategies, eliminating speculation.

“…Power plant boiler is the most complicated industrial component which involved the nonlinear, phase-change and inverse-response performance and plays as an important equipment in modelling and simulation challenge [5]. Boiler inadequacy and abrupt shut downs incur losses to annual revenues and harm other main components [6]. Therefore, each equipment must be maintained efficiently.…”

Steam boiler also known as steam generator is an integral component in thermal power plants requiring effective maintenance scheduling to extend the overall life cycle of the boiler. However, steam boilers are commonly plagued with issues such as boiler shutdown and tube leakage. Industry experts adopted preventative maintenance to overcome the repetition of outage in steam boilers. This method is flawed in the aspect of redundant maintenance activities. The repetition in maintenance activities will lead to reduced work productivity and increased maintenance operational costs. In this study, a maintenance optimization system specialized in ranking, prioritization and optimization based on Analytical Hierarchy Process (AHP) and Particle Swarm Optimization (PSO) are chosen. The AHP is used to rearrange the maintenance activities according to its priority while the PSO is an intelligent swarm used to optimize the operational duration and maintenance cost based on the result formed from AHP after implemented using MATLAB software. This work proposes maintenance scheduling based on minimization of the objectives focusing on the forming new list of the maintenance activities with the optimal operational duration and maintenance cost.
