Combined economic and emission dispatch considering conventional and wind power generating units

Abstract

Summary Combined economic and emission dispatch (CEED) is an optimization solution to the short‐term demand and supply balancing in the power network. Given that wind power is playing an increasing role in the UK, this paper develops a CEED model for a combined conventional and wind power system under the UK energy policies. The proposed model aims to determine the optimal operation strategy for the given system with the consideration of wind power curtailment and reservation and also the environmental aspect, especially the carbon price of greenhouse gases (GHG) and emission limits of decarbonization scenarios. From 2 case studies, increasing the carbon price at a low emission limit leads to an increase in the total cost, but the rate of the increase is mitigated on decreasing the emission limits. Moreover, dispatch is dominated by the carbon price at high emission allowance levels and by the emission allowance at low emission allowances.

“…While, e i and f i model its valve point effect. As obvious from Equation , the second objective of DEED problem is to mitigate total greenhouse gas emissions which generally consist of three major pollutants including sulfur oxides (SO x ), nitrogen oxides (NO x ), and carbon dioxide (CO 2 ) . where, constants γ i , η i , δ i , ξ i , and φ i indicate the emission characteristics of the unit i .…”

“…As obvious from Equation 2, the second objective of DEED problem is to mitigate total greenhouse gas emissions which generally consist of three major pollutants including sulfur oxides (SO x ), nitrogen oxides (NO x ), and carbon dioxide (CO 2 ). 36 where, constants γ i , η i , δ i , ξ i , and φ i indicate the emission characteristics of the unit i. Aggregating two objectives, DEED problem can be mathematically formulated as a nonlinear optimization process, which can be maximized by a single-objective optimization problem using the weighting factor, ω ∈ [0, 1], as stated by Equations 3 to 5.…”

Adaptive fractional-order PID control of PMSG-based wind energy conversion system for MPPT using linear observers

“…The continuously rising of energy demand and the urgent need to mitigate the malignant effects of climate changes resulted from global warming have driven an enormous variety of research interests to harness renewable energy sources in recent years . Meanwhile, the severe issues associated with fast depleting reserves and ever‐growing costs of fossil fuels such as oil, coal, and natural gas are also responsible for the growth and rise of emerging renewable energy applications, including hydro, wind, solar, and biomass …”

“…[1][2][3][4][5] Meanwhile, the severe issues associated with fast depleting reserves and ever-growing costs of fossil fuels such as oil, coal, and natural gas are also responsible for the growth and rise of emerging renewable energy applications, including hydro, wind, solar, and biomass. 6 Thus far, wind energy conversion system (WECS) plays a very crucial role and becomes very popular because of its elegant merits of cleanness, abundance, and wide distribution. 7 Variable speed wind turbine systems are normally based on either (a) doubly fed induction generator (DFIG) 8 or (b) permanent magnetic synchronous generator (PMSG).…”
