This study investigates the techno-economic feasibility of a photovoltaic power plant integrated with hydrogen energy storage and dual-fuel reciprocating engine for gas-to-power power-to-gas operations. The system is optimised maximising constant grid supply, minimising CO2 emissions, lowering levelised cost electricity (LCOE) to assess its value in future landscape. Multi-objective optimisation identified configuration hydrogen-fuelled generator offering 10 MW supply minimal emissions (78 kg/MWh), at LCOE $335.52/MWh. comprises 93 PEM electrolyser, 4 compressor, 29 t compressed storage, within limits industry's current or projected capacities. A key highlight engine-based approach ability readily enhance through increased diesel consumption without significantly impacting LCOE, provided stay acceptable sector cap. flexibility surpasses alternative technologies. Further analysis explored potential reductions using global data, bringing values down $138.76/MWh, making it competitive market prices. Sensitivity revealed LCOE's highest sensitivity discount rate, followed by impact from variations fuel prices due configuration. Furthermore, tightening emission do not affect system's performance, except limiting maximum achievable 2050 reliance.

The electrification of heating, and in particular district heating networks, is challenging from system integration cost perspectives but could provide significant services for the wider electricity system. In this work, several control strategies are compared optimal design a high-temperature, power-constrained electrified network university campus with borehole thermal energy storage grid such as flexibility, load-levelling wind curtailment mitigation. proposed heat plant operation modelled TRNSYS its performance analysed operator end-user's viewpoint. impact parameters investigated sensitivity analysis. It shown that, depending on strategy, total efficiencies up to 200 % curtailed fractions 43.8 achievable great flexibility load-levelling, operating costs emissions significantly lower than gas-reliant systems. A strategy which aims maximal headroom be best suited perspective both end-user (efficiency, cost) (grid services). compromise between efficiency highlighted mitigated by financial incentives integration, benefiting consumers operators.

The heating periodicity control strategy of the combined heat and power-coupled energy storage system

Energy Sources Part A Recovery Utilization and Environmental Effects, Год журнала: 2024, Номер 46(1), С. 12112 - 12129

Опубликована: Авг. 26, 2024

Most analyses on heating strategies for power plants rely a 24-hour periodicity technique, simplifying the examination of entire season to that single-day''s strategy. Addressing this limitation, study in paper uses various periodicities as metrics strategies, investigating their impacts system. To facilitate simulating heat load data across different periodicities, author introduces supplementary simulation method utilizing MATLAB-EBSILON. This approach enables rapid and efficient computation extensive sets. Various influence system primarily terms natural gas consumption. While longer result more significant savings, they also escalate demand energy storage The research results show with electricity prices between 0.3 0.5 yuan/kWh ranging from 3.4 4.2 yuan/m3 12-hour is identified economically optimal strategy region studied article. can save about 7% than conventional periodicity.
