Abstract
Capable of aggregating multiple energy resources, the energy service company (ESCO) has been regarded as a promising alternative for improving power system flexibility and facilitate the consumption of renewable resources in the energy market. However, the issues have become significantly more serious related to the privacy and security of the data in consumption and trading. In this paper, we address the problem by proposing a privacy-preserving energy scheduling (PPES) model based on energy blockchain network. A Lagrangian relaxation method is applied to decompose the model into several individual optimal scheduling problems, and the individual scheduling problems are solved by consensus algorithm and smart contracts in energy blockchain network. The performance of the proposed model and method is evaluated with several case studies based on multiple energy nodes. Simulation results show the rationality and validity of the proposed method, and the model is conducive to the protection of environment and transparent scheduling of energy service companies (ESCOs). In addition, it can reflect the information of energy demand and supply to improve the privacy and security of data.

Nowadays, efficient energy conservation and emission reduction is put out in a primary strategic position due to the climate variation and sustainable development
Based on the blockchain technology and the concept of energy service company (ESCO), this paper proposes a model of energy blockchain network, which plays the role of information exchange and integrate to reduce the credit cost in the trade
Intel Core i5-3320 M processor, this paper takes two energy scheduling simulations and comparison analysis processes as examples to verify the characteristic of the energy blockchain blockchain network (EBN)-individual ESCO model (IESCOM)
Summary
Efficient energy conservation and emission reduction is put out in a primary strategic position due to the climate variation and sustainable development. Renewable energy resources cannot directly participate in the trade in a deregulated energy market due to their intermittency [2,3] Traditional integration conceptions, such as load aggregator (LA) and virtual power plant (VPP), are only used to manage the distributed energy resources in an electrical power system [4], and they are difficult to meet the diversified demands of end users. In this situation, as the integration conception of energy service, the energy service company (ESCO) is put forward, which is defined as a public or private company providing commercial, technical, and financial services for end users [5]. ESCOs can render high effective management for multiple energy coupled system in order to stabilize the system operation and reduce the maintenance cost [6,7]
