Power systems have been undergoing significant restructuring as a result of increasing independently operated local resources. Consequently, new entities, i.e. microgrids (MGs), are developed, which facilitate the integration of local resources, specifically renewable energy sources (RESs), into the operation of power systems. Despite many benefits, the integration of RESs could cause severe rampings in the net-load, which would challenge the reliable operation of the system. Therefore, it seems essential that flexible local resources in an MG should be employed to provide flexibility services to the main grid, thus ensuring that ramping in the MG's net-load would meet the ramping capability in the upper-level system. Accordingly, this study aims to develop an energy management framework to schedule local resources in an MG considering system's ramping limits. In this regard, the interaction between electricity and gas grid as a potential future flexible resource for energy systems is considered in the developed scheme. Moreover, the chance-constrained methodology is employed to address the uncertainty associated with the operational management of RESs. Finally, the proposed energy management model is analysed from different perspectives to show the importance of the contribution of flexible local resources to the efficient improvement of the power system flexibility.

Summary Reduction in greenhouse gases and electricity is a major concern of developing countries in the present scenario. Therefore, energy demand reduction through conservation voltage reduction (CVR) scheme can play a prominent role in such concerns because a major share of energy demand in developing countries is still met by conventional coal/fuel‐based power plants. Moreover, it does not require the participation of consumers to achieve energy saving, unlike in demand side management. Therefore, in this paper, a coordinated scheme comprising multiple voltage‐regulated devices such as on‐load tap changer (OLTC) transformer and switched capacitor banks (SCBs) including distribution network reconfiguration (DNR) operation for CVR has been proposed with minimum operating cost in distribution system. In addition, the impact of a flexible power electronic device called soft open point (SOP) has been investigated during CVR operation. The objective function of the proposed coordinated CVR scheme is to minimize the operating cost, which include the energy demand cost, switching operating cost of OLTC, SCBs, and remote‐controlled switches (RCSs), carbon emission cost, and operating and maintenance costs of SOP, while satisfying the system operational constraints. Further, the impact of high penetration of photovoltaic (PV) distributed generation on the proposed coordinated scheme has been studied. Besides, local reactive power voltage (Q‐V) control strategy of the SOP inverter has been proposed to mitigate voltage violations during cloudy day conditions. The present optimization problem has been solved using modified binary grey wolf optimization (MBGWO) algorithm. The performance of the proposed scheme has also been verified considering the forecast errors in PV generation and load demand. The proposed coordinated CVR scheme has been implemented on a modified 69‐bus distribution system. The test results demonstrate the significance of the coordinated scheme for the minimization of daily operating cost. The comparative study reveals that the combined impacts of CVR, DNR, and SOP are more beneficial than that of either CVR, DNR, or SOP operation.

“…The decarbonization of the electricity sector involves the transformation of the entire generation system, with increasing reliance on renewable energy sources (RES) [1]. The intermittency of traditional stochastic RES and the inevitable errors in their prognosis create increased flexibility requirements, impacting the economic operation and security of the system [2][3][4], while curtailments in RES production constrain the exploitation of available potential under high RES penetration rates, [5]. Within this context, energy storage is an enabling factor to achieve the fast and effective decarbonization of energy systems, relying primarily upon stochastic RES production, [6][7][8][9][10].…”
