“…With the ever-increasing use of renewable power, the power system network now is not only allocating system 13 power from conventional generators but also from renewable power plants, such as wind farms [23,24], solar 14 PV plants [25,26] and hydro power stations [27,28]. Nowadays, wind power is in the top two of the renewable 15 energies in the UK and its capacity is still increasing [29].…”

With the increasing issues in the environmental and the high requirement for energy, the Energy Market Reform (EMR) was introduced by the UK government. This paper develops a novel Dynamic Economic and Emission Dispatch (DEED) model for a combined conventional and wind power system incorporating the carbon price floor (CPF) and the Emission Performance Standard (EPS) that is supported by the EMR. The proposed model aims to determine the optimal operation strategy for the given system on power dispatch taking into account wind power waste and reserve and also the environmental aspect, especially the CPF of greenhouse gases and the emission limit of the EPS for different decarbonisation scenarios. Case studies for the demand profile in the Sheffield region in the UK with different time intervals is presented. The results indicate that renewable power is superior in both the economics and emissions to a mid to long-term energy strategy in the UK.

A hybrid energy storage system (HESS) plays an important role in balancing the cost with the performance in terms of stabilizing the fluctuant power of wind farms and photovoltaic (PV) stations. To further bring down the cost and actually implement the dispatchability of wind/PV plants, there is a need to penetrate into the major factors that contribute to the cost of the any HESS. This paper first discusses hybrid energy storage systems, as well as chemical properties in different medium, deeming the ramp rate as one of the determinants that must be observed in the cost calculation. Then, a mathematical tool, Copula, is explained in details for the purpose of unscrambling the dependences between the power of wind and PV plants. To lower the cost, the basic rule for allocation of buffered power is also put forward, with the minimum energy capacities of the battery ESS(BESS) and the supercapacitor ESS(SC-ESS) simultaneously determined by integration. And the paper introduces the probability method to analyze how power and energy is compensated in certain confidence level. After that, two definitions of coefficients are set up, separately describing energy storage status and wind curtailment level. Finally, the paper gives a numerical example stemmed from real data acquired in wind farms and PV stations in Belgium. The conclusion presents that the cost of a hybrid energy storage system is greatly affected by ramp-rate and dependence between the power of wind farms and photovoltaic stations, in which dependence can easily be determined by Copulas.

“…[11][12][13][14][15][16] Although the optimization algorithms are different, most of these studies used multi-objective optimization to accomplish the balance between cost and emission minimizations. With the everincreasing use of renewable power, the power system network now is not only allocating system power from conventional generators but also from renewable power plants, such as wind farms, 17,18 solar PV plants, 19,20 and hydro power stations. 21,22 Due to the negligible emissions in renewable power generation, the dispatch of renewable resources does not have emission dispatch.…”

“…In order to determine the uncertainty in wind power, some research has been performed on modelling the stochastic nature of the wind speed and the penalty and the reserves of wind power cost. 17,18,23,25 First of all, Hetzer et al 23 created a new ED model of a combination of the conventional power and wind-powered generators. They introduced direct, penalty, and reserves wind power costs in to the ED problem.…”

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.
