Special Issue Information

Dear Colleagues,

The continued growth of renewable energies and their integration to the power grids, especially through distributed integration, has increased the importance of electrical power control and management. In addition to distributed integration of the renewables, the increasing applications of the recent technology of light-emitting diodes (LEDs) and resultant power electronics have impacted power quality as well. As such, power quality analysis has an important role to play not just in power management but also in the final electrical power quality delivered to customers. This Special Issue invites researchers in the fields of power control and management, renewable power distribution, and power quality measuring and control to submit their quality research works for publication. The Special Issue includes but is not limited the following topics:

  • Renewable energy management;
  • Distributed power generation;
  • Power system control;
  • Power system generation planning;
  • Power system transmission planning;
  • Optimized power systems;
  • Optimization of the power system planning;
  • Electrical power quality measurement;
  • Power systems harmonics and inter-harmonics measurement;
  • Power system sub-harmonics measurement;
  • Supra-harmonics interference to electrical power.

This paper proposes a methodology to develop generation expansion plans considering energy storage systems (ESSs), individual generation unit characteristics, and full-year hourly power balance constraints. Generation expansion planning (GEP) is a complex optimization problem. To get a realistic plan with the lowest cost, acceptable system reliability, and satisfactory CO2 emissions for the coming decades, a complex multi-period mixed integer linear programming (MILP) model needs to be formulated and solved with individual unit characteristics along with hourly power balance constraints. This problem requires huge computational effort since there are thousands of possible scenarios with millions of variables in a single calculation. However, in this paper, instead of finding the globally optimal solutions of such MILPs directly, a simplification process is proposed, breaking it down into multiple LP subproblems, which are easier to solve. In each subproblem, constraints relating to renewable energy generation profiles, charge-discharge patterns of ESSs, and system reliability can be included. The proposed process is tested against Thailand’s power development plan. The obtained solution is almost identical to that of the actual plan, but with less computational effort. The impacts of uncertainties as well as ESSs on GEP, e.g., system reliability, electricity cost, and CO2 emission, are also discussed. Full article

Penetration of equipment such as photovoltaic power generations (PV), heat pump water heaters (HP), and electric vehicles (EV) introduces voltage unbalance issues in distribution systems. Controlling PV and energy storage system (ESS) outputs or coordinated EV charging are investigated for voltage unbalance compensation. However, some issues exist, such as dependency on installed capacity and fairness among consumers. Therefore, the ideal way to mitigate unbalanced voltages is to use grid-side equipment mainly. This paper proposes a voltage unbalance compensation based on optimal tap operation scheduling of three-phase individual controlled step voltage regulators (3ϕSVR) and load ratio control transformer (LRT). In the formulation of the optimization problem, multiple voltage unbalance metrics are comprehensively included. In addition, voltage deviations, network losses, and coordinated tap operations, which are typical issues in distribution systems, are considered. In order to investigate the mutual influence among voltage unbalance and other typical issues, various optimization problems are formulated, and then they are compared by numerical simulations. The results show that the proper operation of 3ϕSVRs and LRT effectively mitigates voltage unbalance. Furthermore, the results also show that voltage unbalances and other typical issues can be improved simultaneously with appropriate formulations. Full article
