Executive Summary
The long-term system development planning is a key element to ensure the reliable future operability. Technologies for generation and demand develop continuously (RES, EV, large scale BESS etc.) thus enforcing the power system to evolve and adapt to new requirements and challenges.
The procedures and methodologies for long-term plan and planning scopes formation enable to:
– point in the right direction of the power system development.
– enhance smooth and seamless shift from one prevailing technology to another.
– provide a unified technical policy.
– develop and duly implement technical solutions to meet changing system needs.
– ensure transparency of decisions, and as a result.
– gain consensus between regulatory authorities and utilities for adopting appropriate plans.
Global energy transition aimed at carbon footprint reduction mainly in the electricity industry and globalization of power systems will definitely require transformation of methods and approaches to system development planning as well as significant financial resources with additional requirements not only to the development planning, but mostly to its quality. Due to the specifics of each country’s power system and the differences in regulation and levels of current and prospective technologies for generation and demand development exchange of experience and data remain crucial to achieve maximum progress at minimal costs, considering the challenges the long-term system development faces.
The aim of the questionnaire is to ensure the exchange of accumulated best practices in the field of system planning, in the light of energy transition and new challenges the industry meets.
The results of the questionnaire show that the predictable variety of power systems and applied methodologies compliments a lot of common tasks and overlapping approaches, generated by similar issues (regarded challenges and their aspects) and initial conditions (lack and quality of input data) as well as by similar features of demand forecast methods or issues of developing special methodologies for RES balancing.
A more detailed additional joint study of these issues is useful and highly recommended. Considering the significant impact of economic factors on the development of the industry, it is important to establish strong principles and approaches for the selection of technical solutions, which will ensure reasonable balance between technology and economy.
Such principles can be set as reliability criteria. The security requirements enhance reliable operation and unify approaches to the system development planning. At the same time, these requirements directly affect the economic component of the system development and determine the financial issues. Thus, approaches to reliability assessment and decision-making principles in the industry require joint efforts of all members for more detailed analysis. Further teamwork on the issue will be rather efficient.
