With the improvement of residents’ living standards, the cooling and heating load are increasing rapidly, and the influence of temperature on the unified scheduling electricity consumption is increasing. Based on the temperature gradient change, the monthly unified scheduling electricity consumption prediction research is carried out to quantify the influence of temperature on the unified scheduling electricity consumption, and the unified scheduling electricity consumption prediction is performed for a provincial power grid. The example further proves the feasibility and effectiveness of the prediction method.

As the installed capacity of wind power increases rapidly, how to promote wind power curtailment (WPC) integration has become a concern. The surface and underlying causes of wind power curtailment are insufficient peaking capability of the power system and imperfect peaking compensation mechanisms, respectively. Therefore, this paper proposes a peaking compensation mechanism uniting supply side and demand side to enhance system peaking capability. Firstly, through incentive and fairness analysis, the interest relationship of peaking subjects is researched based on game theory, and the peaking contribution on supply/demand side is quantified by Pearson correlation coefficients. Secondly, based on clustering analysis, the potential of system peaking providers are explored adequately, supply-side thermal units are divided into deep peaking clusters, and demand-side demand response (DR) resources are integrated into virtual peaking plants (VPP). Accordingly, a two-stage wind-thermal-VPP coordination optimization model is built to dispatch peaking providers. Furtherly, a two-layer peaking compensation allocation method considering peaking contribution and peaking enthusiasm is proposed to encourage peaking providers and mitigate “combination explosion”. Simulation results indicate that the proposed mechanism effectively promotes the enthusiasm of union peaking and the integration of WPC.

The electricity retail market reform is the most active field in the new round of power system reform. It is necessary to speed up the formation and development of the electricity retail companies, to study its business classification supervision and development mode, and to improve the management and operation efficiency of the electricity retail companies. Therefore, according to the experience of domestic and foreign retail market reform, this paper studies the business strategy and business development model of electricity retail companies participating in market competition in the opening electricity retail market. According to the policy framework of the new round of power system reform, the classification and characteristics of the electricity retail companies are clarified, and the different ways of participating in the market competition are studied. Secondly, considering the value of users’ energy, the degree of market participation, and the grade of telecommunication, the model of multi-value level of electricity users is established. Finally, based on the diversification of electricity retail companies and the choice of customers, the paper puts forward the differentiated management strategies of electricity retail companies from four aspects: service strategy, management strategy, talent strategy and competitive strategy, which will provide strategic reserve and theoretical support for electricity retail companies.
