“…Despite the fact that flexible resources play an important role in integrating RER and thus achieving the carbon reduction trajectory, their carbon intensities vary greatly. For instance, during the startup and shutdown conditions, excessive CO2 is generated from flaring [18], which is considered a major greenhouse source of utilizing fully flexible generators.…”

In the transition to a low-carbon economy, the market share for renewable energy is significantly increasing and gradually substituting traditional energy. The high renewables penetration results in increased balancing action volumes due to system stability requirements. The balancing market (BM) primarily turns down renewable generation and turns up traditional carbon-intensive generation in response to real-time energy imbalance. Existing dual-stage market mechanisms conflict with the carbon reduction trajectory by implementing balancing actions regardless of their carbon footprint. This paper proposes a novel balancing market model by evaluating the negative externality of carbon to coordinate the environmental targets in both markets. Firstly, mathematical models are formulated for key participants in the dual-stage market. The emissions of dispatchable generators and flexible loads are distinguished by their operation modes and flexibility types, respectively. Carbon signals are incorporated into their bid/offer pricing models through the carbon emission flow (CEF) model. By integrating these incentives for carbon reduction, the dual-stage market model is formulated to minimize economic and environmental costs. Simulation results demonstrate that the proposed model effectively reduces carbon emissions in the BM and strike a balance between cost-efficiency and environmental benefits. It enables system operators to incentivize decarbonized energy resources in both stages.𝑇 /,1'2 +2 , 𝑇 /,1'2 +,, Minimum startup and shutdown time for generator 𝑔 𝑈𝑜𝑆 Use of system charge 𝑟 6>8 ,𝑥 6>8 Resistance and reactance of line 𝑏, 𝑗 𝜇 Generation efficiency

“…Most of the reported research has investigated the unit performances based on rich industrial experience (see refs , , and ) and dynamic simulations of the plants (refs , , , and − ) so that different proposed start-up and shutdown strategies have been evaluated separately. Although the end-of-pipe FM approach is well-known in practice, most research has focused on the flare source reduction approach.…”

“…Several start-up strategies with different off-spec recycling streams from downstream units to the CGC inlet were investigated and the best one was identified with respect to the amount of flare emissions. Later in ref they extended the PCFM strategies by considering intermediate storage units to accumulate and recycle off-spec products.

Olefins production plants are large-scale plants, in most of which gaseous and liquid hydrocarbons are cracked to produce light olefins. The complex and large-scale nature of these plants makes it an utmost necessity to design and operate them with the use of computer-aided optimization and control methods. This review paper provides an overview of the reported research works on the optimization and control of different parts of olefin plants. The main research studies are discussed in two main sections: Optimal Design and Process Operation and Control. In the Optimal Design section, the state of the optimal design of cracking furnace systems, cold-end separation systems, and separation columns have been studied. Then in the Process Operation and Control section, the control of cracking furnaces, the control of cold-end separation systems, real-time optimization of olefin plants, cyclic scheduling of cracking furnace systems, production planning of olefin plants, and finally, start-up and shutdown operations in these plants have been extensively reviewed. This paper is a continuation of the three review articles published previously entitled Thermal and Catalytic Cracking of Hydrocarbons for the Production of Light Olefins, the last of which focused on process modeling and simulation.

Summary Energy efficiency optimization and energy management can bring multiple economic benefits for the complicated petrochemical industries. However, the influence of the production scale and materials, and the uncertain data have a direct impact on the production prediction and energy efficiency optimization of ethylene production process, which is ignored by the conventional optimization strategies. To achieve energy management and reduce energy consumption considering the production technology, total energy, and material flows, a multiobjective energy efficiency optimization scheme for the ethylene production process with respect to material‐product nexus is proposed. Specifically, a total‐factor material‐product nexus model of the ethylene production is established by a novel functional link prediction error method–integrated algorithm, providing system‐level material equilibrium constraints for the energy efficiency optimization scheme. Then an optimization model with two mutually complementary energy efficiency indicators is established and implemented by the multiobjective particle swarm optimization integrating functional link prediction error method. The proposed energy efficiency optimization scheme is applied into a practical ethylene plant, and the optimization results demonstrate that energy efficiency of this plant is increased by 10.30%, synthetical energy consumption is decreased by 13.05%, and energy cost is decreased by 10.42%.
