The power industry is increasingly affected by several trends, which require improvements in the distributed generation and control systems of on-site power. These trends include the ability to share load across generators more effectively, seamless sequencing of generators, and the ability to monitor and control power that is being produced. Electronic control systems can provide these advantages in a cost effective solution. The application of electronic controls to a power distribution system requires a thorough development program. It is imperative to assure that the controls will provide reliable, long-term performance, as well as meeting the plant’s current and future needs for power distribution. This paper describes the development and field evaluation required to apply electronic controls to existing switchgear and power distribution systems in the power generation industry. The microprocessor based electronic control system for today’s power plants replaces out-dated analog equipment and antiquated relay logic. The new systems incorporate three main functions: Paralleling generators, monitoring power requirements, and effective sequencing of generators in power plants. Integration of these functions into the microprocessor based control system provides increased reliability, reduced cost, and enhanced performance, while concurrently providing increased flexibility in the operation of the plant. Additional benefits can be realized including reduced operator requirements, reduced training costs, and reduced burden on instrumentation electricians. A primary focus of this paper is the process used to qualify the control system needed for specific types of existing distributed power systems. This process consists of current system evaluation and categorization, establishment of classification of plant (utility, merchant plant, peak shaving facility, IPP), and determining the future needs of individual plants for power distribution. Local regulatory and utility protection and interconnect requirements must also be assessed to assure that the new control system meets or exceeds them. Methods of accurately monitoring, improving performance, and providing generator sequencing are defined, including accounting for improvements in the long-term expansion of the distributed power control and monitoring system.

With the advent of a new Precision Time Protocol specification, new opportunities abound for clock synchronization possibilities within power grid control systems. The third iteration of the Institute of Electrical and Electronics Engineers Standard 1588 specification provides several new features specifically aimed at complex, wide-area deployments in which situational awareness and control require precise time agreement. This paper describes the challenges faced by existing technology, introduces the new time distribution specification, and provides examples to explain how it represents a game-changing innovation.

Bidirectional Power Flow

A distributed power system operation and control node privacy and security are attractive research questions that deliver electrical energy systems to the participating stakeholders without being physically connected to the grid system. The increased use of renewable energy in the power grid environment creates serious issues, for example, connectivity, transmission, distribution, control, balancing, and monitoring volatility on both sides. This poses extreme challenges to tackle the entire bidirectional power flow throughout the system. To build distributed monitoring and a secure control operation of node transactions in the real-time system that can manage and execute power exchanging and utilizing, balancing, and maintaining energy power failure. This paper proposed a blockchain Hyperledger Sawtooth enabling a novel and secure distributed energy transmission node in the EPS-ledger network architecture with a robust renewable power infiltration. The paper focuses on a cyber–physical power grid control and monitoring system of renewable energy and protects this distributed network transaction on the blockchain and stores a transparent digital ledger of power. The Hyperledger Sawtooth-enabled architecture allows stakeholders to exchange information related to power operations and control monitoring in a private ledger network architecture and investigate the different activities, preserved in the interplanetary file systems. Furthermore, we design, create, and deploy digital contracts of the cyber–physical energy monitoring system, which allows interaction between participating stakeholders and registration and presents the overall working operations of the proposed architecture through a sequence diagram. The proposed solution delivers integrity, confidentiality, transparency, availability, and control access of the distribution of the power system and maintains an immutable operations and control monitoring ledger by secure blockchain technology.
