Development of Operational Planning Model for Demand-side Energy Resources under Demand Response
The Proceedings of the National Symposium on Power and Energy Systems(2022)
摘要
The energy transition toward carbon neutrality in 2050 is progressing, and attention is being paid to demand-side energy resources to absorb the fluctuations in the output of variable renewable energy. The objective of this research is to construct an easy-to-adopt methodology for virtual power plants that the method can be adopted for arbitrary demand-side energy resources such as district heating and cooling system and water distribution system by using a part of measured process variable values, to respond against demand response signal in any time. The proposed VPP method is composed of a process modelling method for an optimal operational planning problem and a time series forecasting method as well as an optimization algorithm that fulfils the requirements of a given demand response event. This paper represents the three models to identify input-output characteristics of demand-side energy resources. Quadratic polynomials, piecewise linear approximation and discretization by basis coding are taken up as models and their respective characteristics are discussed.
