Locational transmission capacity reserve determination using system well-being analysis

Deterministic-based power grid planning enhancement using system well-being analysis

“…This paper integrates the concept of the locational transmission capacity reserve described in [12] into a practical transmission planning process considering both reliability and economic considerations. The locational transmission capacity reserve is defined as the additional transmission capacity required to deliver the electrical power from remote generation to supply the load demand in a generation deficit area (load dominant area), i.e.…”

“…through the inter-tie lines. In some generation deficit areas that rely heavily on inter-tie lines to access remote generation from neighboring areas, a stringent deterministic security rule such as the N-1-G criterion in which a loss of single transmission component together with a loss of critical local generating unit is considered [12,13]. Another example of N-1-G application is when considering system security under the generating unit maintenance scheduling along with the N-1 contingency condition of the transmission system [14].…”

“…The utilization of the N-1-G security criterion in transmission planning, on one hand, could improve the system reliability. On the other hand, the resulting reliability level associated with this criterion may not be consistent and may involve significant cost if the size of the critical local generating unit in the studied area is quite large leading to a substantial amount of transmission capacity being reserved under the specified security criterion [12]. However, the method presented in [12] only aims at determining the additional transmission capacity required as the reserve for accessing the remote generation to secure the system load based solely on the reliability standpoint while ignoring other relevant technical and economic considerations.…”

“…In contrast, this paper extends the concept proposed in [12] by applying it to a more comprehensive transmission planning process typically employed in practice, where other relevant technical and economic analyses must also be considered. Consequently, the contribution of this paper is aimed at demonstrating that the method presented in [12] is not only technically sound when incorporating the deterministic criteria into the probabilistic framework, but it is also economic justified when applying it comprehensively to the practical transmission planning process.…”

“…Contingency analysis is very important step in planning studies for a power system engineer [17]. It is essential to predict the heavy loads and emergencies which occur in a power system such that suitable action can be taken in predefined time.…”
