“…Generalized additive model for location, scale and shape (GAMLSS) is a well-known distributional regression approach, which has been recently developed and used in different applications [23], [24]. In GAMLSS, one of a variety of density functions can be selected in which the mean, variance and higher statistical moments can be specified dynamically as conditional upon exogenous driving variables.…”

This article presents a new approach for finding the optimal multimarket trading strategy of cascaded hydropower plants (HPPs) in the sequential electricity markets. These markets are day-ahead energy market, the market for frequency containment reserve in normal mode (FCR-N), and manual frequency restoration reserve markets for both energy production and capacity reserve. The active-time duration (ATD) of an mFRR energy offer is an important required parameter and it is uncertain at the time of day-ahead offer-function submission. Hence, we suggest a distributional regression approach for ATD modeling in an optimal multimarket setup. Also, a modified machine learning approach is proposed to generate price scenarios for the mFRR energy market taking into account uncertain ATD parameters. To illustrate our proposed approach, various numerical experiments are performed. Our numerical results show how proper modeling of ATD parameters can lead to a more realistic multimarket offer-function for cascaded HPPs. Furthermore, the results show how the inclusion of FCR-N and mFRR capacity markets change the optimal day-ahead offer-function.

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

Microintegrated energy systems (MIESs) can be disconnected from power distribution systems during power system faults. This paper develops a control scheme for an islanded MIES. The VSC inverter controls the AC bus voltage and frequency using a modified AC voltage regulator and a modified frequency regulator. The control structures of the power-to-gas and PMSG-based microturbine generator (MTG) systems are improved. Renewable generation always runs at the maximum power point. The surplus renewable energy in the MIES can be converted into natural gas using power-to-gas, and the MIES can make full use of renewable energy. The proposed coordinated control scheme of the electrolyzer and the supercapacitor can achieve a power balance of the islanded MIES and reduce the DC-link voltage fluctuation. A micro-gas turbine can provide electric energy to the load and enhance distribution system resilience. A coordinated control scheme of the MTG and the supercapacitor is developed to improve MIES operation. A feature of this paper is the research on fault ride-through of the islanded MIES. A fault ride-through strategy is proposed, where the AC voltage of the VSC inverter is reduced to limit the short-circuit current during AC system faults. Islanded MIES simulations are conducted in a MATLAB/Simulink environment to test the control scheme. The simulation results verify the effectiveness of the control scheme during normal operation and failure.
